Nigeria’s President Muhammadu Buhari has said he is determined to end police brutality, introduce reforms and bring “erring personnel… to justice”.
His comments came after two days of protests sparked by a video of a man allegedly being killed by police.
The protest movement initially targeted the federal Special Anti-Robbery Squad (Sars), widely accused of unlawful arrests, torture and murder.
The protesters say they want the unit disbanded rather than reformed.
In a series of tweets, the president said that his government’s “determination to reform the police should never be in doubt”.
He added that he was being “briefed… on the reform efforts ongoing to end police brutality and unethical conduct”.
But he called for calm and emphasised that most police officers were committed to protecting Nigerians.
On Friday, in the capital, Abuja, police fired tear gas at protesters who were highlighting police harassment and brutality.
A police spokesman said minimum force had been used but demonstrators told the BBC that some people had been beaten and one said she had heard gunshots.
The hashtag #EndSARS was trending worldwide on Twitter on Friday with celebrities including the Nigerian superstars Wizkid and Davido tweeting their support for protesters.
British-Nigerian Star Wars actor John Boyega has also expressed his backing on social media.
‘Targeted for being flashy’
The #EndSARS hashtag was first thought to have been used in 2018, but it emerged once again a week ago following the alleged killing of a young man by officers from the Sars unit.
Many people were using the opportunity to share stories of brutality attributed to the police unit, which has developed notoriety for unduly profiling young people, reports the BBC’s Nduka Orjinmo from Abuja.
Those considered “flashy” often attract the Sars officers’ attention and very few walk away without having to hand over money, while others are arrested or jailed on trumped-up charges and some have been killed, our correspondent adds.
On Sunday, Nigeria’s inspector general of police Mohammed Adamu banned the Sars unit from carrying out stop and search duties and setting up roadblocks.
He also said members of Sars must always wear uniforms and promised the unit would be investigated.
But protesters want the unit disbanded completely.
The National Human Rights Commission published a report into the activities of Sars in May 2019 but critics say little appears to have changed.
