A woman has been arrested for allegedly attempting to smuggle substances suspected to be the psychoactive drug known as “colos” into the Medium Security Custodial Centre, Ibara, Abeokuta, Ogun State.
The Ogun State Command of the Nigerian Correctional Service (NCoS) disclosed this in a statement issued by its Public Relations Officer, Odukoya Olayinka.
According to the statement, the suspect was arrested at about 1:33 p.m. on Friday, August 28, 2026, during a routine screening exercise at the entrance of the custodial facility.
Olayinka said the woman had visited an inmate on death row when correctional officers discovered a sachet of Milo beverage allegedly containing substances suspected to be “colos.”
The suspected contraband was detected during the standard screening process at the facility’s main gate, according to the NCoS.
The Service said the incident underscored the vigilance of its personnel and its commitment to preventing illicit drugs and other prohibited items from gaining access to custodial facilities.
Following her arrest, the suspect was handed over to the National Drug Law Enforcement Agency (NDLEA) for further investigation and possible prosecution in line with established procedures.
The Controller of Corrections, Ogun State Command, Kamoru Adesina, commended the officers involved for their alertness and professionalism.
Adesina reiterated the Service’s zero-tolerance policy towards drug trafficking and other criminal activities within custodial facilities.
He stressed that correctional centres were established to reform and rehabilitate inmates and must not be allowed to become channels for the circulation of illicit substances.
The command also warned members of the public against attempting to compromise the security of correctional facilities by introducing prohibited items.
It added that anyone found engaging in such acts would be dealt with in accordance with the law.
