The police say they have intensified efforts to investigate the threats of explosions issued to two schools in Lagos.

Grange and Avi-Cenna schools in Ikeja were forced to shut down hurriedly last week following the threats.

The police command in Lagos, however, did not provide any details about the source of the threats or the brains behind them.

“It’s still under investigation. The investigation is still ongoing. We can’t give you details on that so that it won’t jeopardise the investigation.

“Any comment we make now might…you know. So, for now, please bear with us. We’ll still update the public as time goes by. But as of now, we can’t make any statement on it,” the police spokeswoman, Abimbola Adebisi, told Peoples Gazette on Monday.

Last week, the police’s anti-bomb squad made a sweep of the facilities and gave them a clean bill of health.

Ms Adebisi said the human resources managers and chief security officers of both schools had, on Wednesday, informed the police headquarters of the threats received via WhatsApp with the same numbers.

“Upon receipt of the reports, the Commissioner of Police, CP Olohundare Jimoh, immediately mobilised and personally led a team of police operatives, including a team of experts from the Command’s Explosive Ordnance Disposal, Chemical Biological Radiological and Nuclear, the Rapid Response Squad, and other tactical teams, to the school premises for on-the-spot assessment and security reinforcement.

“A painstaking and comprehensive sweep of the entire school environment, including classrooms, administrative offices, halls, playgrounds, and surrounding premises, was conducted by the EOD-CBRN experts to rule out the presence of improvised explosive devices or any other dangerous or suspicious materials.

“The operation yielded no explosive or hazardous device, and the schools were consequently declared safe for continued academic and administrative activities,” Ms Adebisi explained.
