Nigeria’s National Drug Law Enforcement Agency (NDLEA) says it has dismantled a suspected industrial-scale methamphetamine laboratory in Ebonyi State and arrested a Mexican national linked by investigators to a wider network of clandestine drug laboratories.
The agency said Arturo Carrera Loaiza was arrested on August 19 while allegedly attempting to leave Nigeria through Murtala Muhammed International Airport in Lagos. The development was announced by the NDLEA on September 15 following months of investigation.
The agency described Loaiza as a suspected key figure in the network. That description is an allegation by the NDLEA, and the suspect has not been convicted in the matter.
How the investigation began
According to the NDLEA, the investigation developed from earlier operations involving suspected methamphetamine laboratories in Ogun and Oyo states.
On May 16, the agency said it arrested three Mexican nationals and seven Nigerians at a forest location in Ogun State.
A month later, on June 17, NDLEA operatives said they arrested another Mexican national, Jose Villa Ochoa, alongside four Nigerian collaborators at a suspected clandestine laboratory in Tapa village, Ibarapa North Local Government Area of Oyo State.
The agency said its investigation subsequently identified Loaiza as a person allegedly connected to the recruitment of the Mexican methamphetamine specialist.
Suspected laboratory discovered in Ebonyi
The NDLEA said information obtained during the investigation led its officers to a property under construction at Isiata Ugoni Okposi in Ebonyi State.
A search of the property on August 30 allegedly uncovered evidence of a clandestine operation.
According to the agency, investigators also reviewed CCTV footage from the location and identified activity involving people and materials associated with the suspected operation. Further intelligence reportedly led officers to another property in a neighbouring community, where some of the materials had allegedly been moved.
The agency said its subsequent raid resulted in the recovery of suspected methamphetamine and laboratory equipment.
NDLEA reports large chemical haul
The NDLEA said officers recovered a substantial quantity of chemicals and equipment from the suspected operation.
Its published account lists 442.8kg of acetone, 37.1kg of toluene, 200kg of P2B, hydrochloric acid, ethanol and other chemical substances, alongside equipment including dehydrators, condensers, pumps, weighing scales, mixers, drums and gas burners.
The agency said one dehydrator contained loose material it identified as methamphetamine.
These substances and equipment have been described by authorities as evidence connected to suspected illicit production. Their presence alone does not establish the guilt of every person named in the investigation.
NDLEA links Ebonyi operation to wider network
The agency said the Ebonyi operation was part of a broader investigation rather than an isolated raid.
NDLEA Chairman Mohamed Buba Marwa, through the agency’s Director of Media and Advocacy, Femi Babafemi, said investigators were pursuing the wider network, including alleged financiers and local collaborators.
The agency has linked the Ebonyi investigation to earlier operations in Ogun and Oyo, where it said Mexican nationals and Nigerian collaborators were arrested.
The repeated involvement of foreign nationals is one reason the NDLEA is treating the investigation as a possible transnational trafficking and production network.
Why the operation matters
Methamphetamine is a powerful synthetic stimulant, and clandestine production creates both drug-trafficking and public-safety concerns.
For Nigerian authorities, the discovery of suspected production facilities is different from intercepting drugs entering the country. A laboratory can potentially provide a domestic production base and reduce the need for finished drugs to be imported.
The NDLEA has said it is particularly concerned about attempts to establish clandestine laboratories in forests and rural communities.
The agency has also encouraged residents in such areas to report suspicious activity, unusual chemical odours and unfamiliar structures.
The arrests do not establish guilt
The case remains an investigation.
The NDLEA has made allegations against Loaiza and other individuals in connection with the suspected network, but those allegations must be distinguished from a court finding.
An arrest or accusation does not establish criminal guilt. Any eventual prosecution would have to establish the relevant allegations through the judicial process.
This distinction is particularly important in reporting drug investigations because multiple people can be investigated or arrested while their individual roles and legal responsibility remain to be determined.
Earlier Oyo operation
The Ebonyi investigation follows another major NDLEA operation in Oyo State.
In June, the agency said it dismantled a suspected industrial-scale methamphetamine laboratory in a forested part of Tapa village and arrested five people, including Mexican national Jose Villa Ochoa and four Nigerians.
The NDLEA described the facility as a highly organised operation and said forensic examinations confirmed the presence of methamphetamine.
The agency’s account of the Oyo operation formed part of the evidence and intelligence it later used in the wider investigation.
Nigeria’s anti-drug challenge extends beyond methamphetamine
The latest operation comes during a broader period of activity by the NDLEA against different forms of drug trafficking.
The agency reported other recent operations involving cocaine, heroin, cannabis, opioids and methamphetamine across several Nigerian states. Its September 2026 news updates also include a report of a South African woman receiving a 40-year prison sentence for importing 5.75kg of heroin into Nigeria.
These cases involve different substances and circumstances, so they should not automatically be treated as part of the same network.
They do, however, show the range of trafficking and drug-production investigations currently being pursued by the country’s anti-narcotics agency.
What happens next
The NDLEA says its investigation into the suspected network is continuing.
The agency has indicated that it intends to pursue other people it believes are connected to the operation, including alleged financiers and local facilitators.
The legal process will ultimately determine the status of the allegations against the arrested individuals.
For now, the confirmed development is that the NDLEA says it has dismantled a suspected industrial-scale methamphetamine laboratory in Ebonyi and arrested a Mexican national in connection with its investigation.
The case also highlights the growing attention Nigerian authorities are placing on suspected domestic production facilities rather than focusing solely on drugs entering the country.
