Four Nigerian policemen have appeared in court in the first public hearing over the killing of radical Islamist leader Mohammed Yusuf in 2009.
The Boko Haram leader was captured alive in Maiduguri and paraded in front of video cameras, but his body was later displayed riddled with bullets.
Legal proceedings began earlier this year but the hearings were kept secret. The trial has now been adjourned until next Tuesday when a fifth officer will be included in the trial and formal charges will be made against the men.
The Nigerian government is often accused of failing to prosecute police accused of brutality and extra-judicial killings.
Two years ago, Nigeria's security forces brutally suppressed an uprising by Boko Haram, destroying their compound and then capturing Mr Yusuf.
Instead of disappearing, the group, which opposes Western education and fights for Islamic rule, re-emerged last September and vowed to avenge its leader's death.
