THE Nigeria Police Force (NPF) has announced the successful extradition of Benjamin Best Nnayereugo, known as ‘Killaboi’, from Doha, Qatar, to face murder charges in Nigeria.
Nnayereugo is accused of killing his 21-year ex-girlfriend, Augusta Oseodion Onuwabhagbe, in Lagos on July 13, 2023.
A statement by the Nigerian Police Force, on Saturday, April 19, stated that the extradition was the result of a coordinated effort between Nigerian authorities, INTERPOL National Central Bureau (NCB), Qatari authorities, and the Ministry of Justice.
It noted that the accused was flown back to Nigeria in the early hours of Saturday, April 19, 2025, after being trailed for months across multiple regions.
The statement stressed that the INTERPOL Red Notice was issued for his arrest in October 2023, and authorities soon discovered that Nnayereugo had been moving under various aliases across West Africa, East Asia, and the Middle East.
“The extradition followed a petition from the family of the deceased, submitted through their legal representatives dated 29th September 2024. The matter was assigned to INTERPOL NCB Abuja for investigation.
“Investigations revealed that the suspect, Benjamin Best Nnayereugo, murdered Miss Onuwabhagbe, a 21-year-old first-class student of Lead City University, Ibadan, at his residence located at No. 24A Abiola Apooyi Street, Oral Estate, Ajah, Lagos, on 13th July 2023. After committing the crime, he fled Nigeria and later released an online video purporting to confess to the act, a deceptive strategy to derail investigative efforts.
“Following his declaration as wanted by the NPF Lagos State Criminal Investigation Department (SCID) on 13th October 2023, an INTERPOL Red Notice was issued for his global apprehension. He was initially arrested in Freetown, Sierra Leone, on 20th October 2023 under the false identity “KANU PRINCETON SAMUEL,” but escaped custody during a prison break on 26th November 2023 in Feeetown,” the statement read.
His final destination was Doha, Qatar, where he allegedly used the name “Toure Abdoulaye” with a fraudulent Guinean passport.
According to the police, the Qatar authorities arrested him in February 2025, and following a formal extradition request, he was repatriated to Nigeria. His arrest in Doha followed biometric confirmation of his identity.
Background
Nnayereugo had been on the run after allegedly stabbing Onuwabhagbe during an argument at his residence in the Ikota area of Lagos.
Following the incident, he reportedly posted a series of Instagram messages in August 2023, admitting to the crime and expressing remorse.
Nnayereugo confessed via his Instagram account @Killaboigram_ saying that “I got into an argument with my girlfriend @austa xxo which fight I mistakenly stabbed her and ran away out of fear and been suicidal since then (sic).
“I intend to end my life now cause I have lost the one I cherish so much. I want to do the right thing and turn myself in. I will gladly die by paying with my life now,” he wrote on his Insta Stories.”
The police described his posts as an attempt to derail investigations.
