ABUJA (Reuters) - Nigeria’s president will do what it takes to prevent a repeat of demonstrations against police brutality last month that led to unrest in which dozens of protesters and police were killed and more than 200 buildings torched, the police minister said. Protests against an elite police force, the Special Anti-Robbery Squad, or SARS, led last month to the worst civil unrest in Nigeria since the return to civilian rule in 1999. Thousands of Nigerians took to the streets under the slogan “ENDSars” to protest against the force, which the demonstrators blame for killings, torture and extortion. Though the protests were initially peaceful, demonstrators in an upmarket Lagos district were shot at on Oct. 20 by men witnesses said were soldiers. Rights group Amnesty international said 12 protesters were killed. The army denied involvement. In days of unrest that followed, police said 22 of their personnel were killed and 205 buildings including police stations were damaged. “Mr President assured Nigerians that he will do whatever it takes to ensure the repeat of ‘ENDSars’ protests does not occur in Nigeria again,” Police Minister Muhammad Dingyadi told reporters on Tuesday after a meeting of security officials and President Muhammadu Buhari in the capital, Abuja.
