Dabiri-Erewa reiterated President Muhammadu Buhari’s calls to Nigerians to avoid crimes like drug peddling which attracts stiff penalties, sometimes death,
She noted that the latest killing had increased the number of Nigerians killed in South Africa through extrajudicial means in the last one year.
“The barbaric behavior of the perpetrators is not only unacceptable, but also calls for urgent attention by diplomatic authorities in Nigeria and South Africa”, she said.
Dabiri-Erewa urged the South African government to ensure that justice prevails by carrying out investigation and bring the culprit to book.
She reiterated her calls to Nigerians living abroad to always respect the laws of their host countries and be good ambassadors of Nigeria.
“My heart goes out to the families of the deceased and pray God to grant the departed soul eternal rest”, the SSA prayed.
Bartholomew Eziagulu, Chairman of the Nigerian Union in the province, told the Newsmen on Friday that Mr Ikeri was allegedly tortured to death by the police.
He said the union’s investigations revealed that the police arrested the deceased and a friend on suspicion that they were carrying hard drugs.
He said while interrogating him, the police used plastic to cover his face to extort information from him.
“In the process, they suffocated the deceased. When the police took him to the hospital, he was confirmed dead,” he said.
Adetola Olubajo, the Secretary General of the union, said the national secretariat had been informed about the death of the Nigerian.
He said the body had informed appropriate Nigerian authorities and the police in South Africa.
