The young man suspected of blowing himself up inside a Cairo chapel during Sunday Mass, killing at least 24 people, had been arrested and beaten by police two years ago after allegedly taking part in an Islamist demonstration, his lawyer has said.
If independently confirmed, Mahmoud Shafiq Mohammed Mustafa would be the latest Egyptian to be radicalised after being subjected to police abuse, a practice that was common for decades and has become rampant after a crackdown on dissent following the military's 2013 ousting of an Islamist president.
