Correctional officers reportedly discovered suspected ‘Colos’ concealed inside a sachet of Milo during routine screening of a visitor

A woman has been arrested for allegedly attempting to smuggle a substance suspected to be a psychoactive drug into the Medium Security Custodial Centre, Ibara, Abeokuta, Ogun State.

The suspect was reportedly arrested at about 1:33 p.m. on Friday, August 28, 2026, during a routine screening exercise at the entrance of the custodial facility.

The Ogun State Command of the Nigerian Correctional Service (NCoS) disclosed the arrest in a statement signed by its Public Relations Officer, Odukoya Olayinka.

According to the command, the woman had visited an inmate at the facility who is classified as a death-row inmate.

During the mandatory screening conducted by correctional officers, a sachet of Milo beverage reportedly attracted attention. Upon closer inspection, officers allegedly discovered that the sachet contained a substance suspected to be “Colos,” a psychoactive substance.

The discovery led to the immediate arrest of the visitor for questioning and further investigation.

The correctional service said the incident underscored the importance of its routine screening procedures, particularly at custodial facilities where visitors are required to undergo checks before gaining access to inmates.

The command did not disclose the identity of the suspect or provide further details on the quantity of the suspected substance recovered.

Authorities have continued to tighten security around custodial facilities across the country to prevent the smuggling of prohibited items, including illicit drugs, weapons and other materials that could compromise the safety and order of prisons.

The NCoS has repeatedly warned visitors and other members of the public against attempting to introduce prohibited items into correctional facilities, stressing that such actions could attract criminal sanctions.
