The Friday incident reportedly impacted more than 100 students and teachers across at least seven schools, including Our Ladies Grammar School, Epe Garage; Anglican Girls Grammar School, Obalende; Titilayo Agbaje Comprehensive High School, Imosan; Ifesowapo Comprehensive High School, Imosan; St. Peter’s Anglican Primary School, Imosan; St. Anthony Grammar School, Esure; and Orphanage Primary School, Imosan.

The development comes just six weeks after a similar chemical odour incident at Our Lady of Apostles Primary and Secondary Schools (OLAS), where 30 students and two teachers were hospitalised.

In a statement released through the command’s spokesperson, DSP Oluseyi Babaseyi, the State Commissioner of Police, Bode Ojajuni, assured residents that the situation has been contained.

Ojajuni disclosed that the Police Explosive Ordnance Disposal (EOD) Unit and other tactical teams were immediately deployed to secure the affected locations, assist emergency responders, and protect the public.

He stated that the situation is now under control, while monitoring and technical evaluations are ongoing.

According to him, the incident came to light when patrol officers in the area received reports of a suspected chemical emission affecting students and residents in parts of Ijebu-Ode.

He added that all affected victims were swiftly evacuated to the General Hospital and private medical facilities for urgent treatment, confirming that no deaths were recorded and that all victims are responding well to medical care.

Preliminary environmental checks from the state’s Air Quality Monitoring infrastructure reportedly detected elevated methane gas levels within the affected zone, while experts and emergency agencies continue investigations to identify the exact source and evaluate possible environmental dangers.

Meanwhile, the General Manager of the Ogun State Environmental Protection Agency (OGEPA), Kehinde Bello, described the incident as more of a security matter than a direct safety threat.

Bello dismissed claims that widespread air pollution caused the incident, stressing that the situation was limited to certain schools rather than the entire Ijebu-Ode community.

Speaking during visits to St. Anthony Grammar School, Esure, the State General Hospital, Esure, and a private hospital in the town, Bello urged parents, guardians, and residents to stay calm, assuring them that the government is actively working to resolve the situation.
