Kolade Johnson was shot dead by Inspector Olalekan Ogunyemi, while he was watching a Premier League fixture between Liverpool and Tottenham Hotspur in Lagos on Sunday.
The Nigerian Police Force on Thursday dismissed Inspector Olalekan, attached to Special Anti-Robbery Squad (SARS) of the Lagos State Police Command.
Ogunyemi was arraigned for murder on Friday hours after an orderly room trial found him guilty of unlawful use of firearms.
The police prosecutor, Inspector Kehinde Olatunde, had told the court that the defendant committed the offence on March 31, at 5:10 pm on Onipetesi Estate, Idi-Mangoro, Lagos.
He said Ogunyemi used his Ak-47 rifle to kill Johnson, adding that the offence contravened Section 223 of the Criminal Law of Lagos State, 2015.
The plea of the defendant was not taken by the court.
The counsel, Sola Adeyemi, had urged the court to remand the defendant for the next 14 days as against the 30-day remand application filed by the prosecutor.
The presiding magistrate, Mrs A.O. Salawu granted the application of the prosecutor.
She ordered that Ogunyemi be remanded in Ikoyi Prisons pending advice from the State Director of Public Prosecutions and adjourned the case till May 6, 2019.
