An Egyptian policeman was arrested Sunday for having shot dead an Islamist detained in a Cairo hospital with injuries from his arrest, the interior ministry said. The ministry, on its Facebook page, said the victim was a member of the outlawed Muslim Brotherhood arrested as he tried to plant a bomb in the capital's Al-Warraq district, without giving a date.

The suspect had insulted and provoked his police guard in hospital, threatening to kill him. The enraged policeman had shot him dead, it said. The ministry said the policeman was arrested and an investigation opened.
