The Nigeria Police Force has confirmed the extradition of Benjamin Best Nnayereugo, also known as “Killaboi,” from Doha, Qatar, to Nigeria.
Nnayereugo is accused of killing his 21-year-old ex-girlfriend, Augusta Oseodion Onuwabhagbe, at his residence in Ajah, Lagos, on July 13, 2023.
The police disclosed this development in a statement issued on Saturday, April 19, stating that the successful extradition followed collaborative efforts involving the Ministry of Justice, INTERPOL National Central Bureau (NCB) in Abuja, Qatari authorities, and other security agencies.
According to Force Public Relations Officer, ACP Olumuyiwa Adejobi, the process commenced after the victim’s family submitted a petition through their legal counsel on September 29, 2024.
INTERPOL NCB Abuja immediately took over the case for further investigation.
Findings revealed that the suspect fled the country after allegedly committing the murder, later releasing a video online in which he appeared to confess—a move investigators believe was intended to mislead the public and obstruct the case.
The suspect was declared wanted by the Lagos State Criminal Investigation Department on October 13, 2023, prompting the issuance of an INTERPOL Red Notice for his arrest.
He was initially apprehended in Sierra Leone under a false identity on October 20, 2023, but managed to escape during a prison break in Freetown on November 26 of the same year.
Investigations later uncovered that Nnayereugo used forged identities while moving across several regions, including West Africa, East Asia, and the Middle East.
He eventually settled in Doha, Qatar, in January 2025 under the alias “Toure Abdoulaye,” using a fake Guinean passport to secure employment and avoid detection.
With the help of biometric verification and close coordination between INTERPOL NCB Abuja and its Qatari counterpart, authorities were able to confirm his identity.
He was taken into custody in Qatar in February 2025. Following an official extradition request processed through Nigeria’s Ministry of Justice, Qatari authorities approved his return.
The Inspector-General of Police, Kayode Adeolu Egbetokun, praised the cooperation among international partners, noting that such collaboration is crucial in tackling cross-border crime. He also assured the public that Nnayereugo will face prosecution and that the police remain committed to upholding justice and public safety.
