Egypt's embattled government said they will launch an investigation into police brutality, after footage emerged of a man, apparently stripped naked and beaten by authorities, Al Jazeera reported on Sunday.
Interior minister, Mohammed Ibrahim , vowed to investigate the violence  after AP caught the attack on camera and broadcast it on Al-Hayat TV on Friday. However, the minister implied that police were unlikely to be directly implicated in the abuse.
Ibrahim told reporters on Friday that initial results from the investigation show that Hamada Saber, 48, was stripped by "rioters". He did not say whether the proceeding injuries were a result of police violence or of other protestors.
Violence has escalated over the past two weeks, following the second anniversary of the Egyptian revolution . Demonstrators claim that current president, Mohamed Morsi, has reneged on promises of freedom and individual rights since his election.
Politicians from all sides have called for calm, meeting on Thursday to discuss a solution  to the growing violence.
