Olaonipekun slumped and died after submitting her NSCDC promotion examination script at the centre where she took the examination.

A colleague of the deceased who wanted to remain anonymous, said the late officer did not exhibit any sign of sickness before her death.

“She was patriotic, God-fearing and always punctual at work,’’ the colleague said.

The Chief Press Officer of the LCDA, Mr Efe Brumen, described the late NSCDC personnel as disciplined and a lover of professional ethics.

“My dear, you would see late Olaonipekun, also called ‘iya-jeje’ in NSCDC uniform always.

“What baffled me most was that Olaonipekun was active and did not show any sign of sickness before the untimely death,’’ he said.

A trader at the headquarters of the LCDA, Mrs Falilat Alao, told the News Agency of Nigeria (NAN) that the death of the NSCDC officer remained a “mystery.”

“Since her demise, I have been scared. I have gone for medical check-up today. Who knows what might have led to such a death?” she asked.
