Prisoner carves IS slogan on cellmate

A radicalized prisoner allegedly carved an Islamic State slogan into the forehead of a fellow inmate in Australia, reports said on Monday, but officials denied extremism was a problem in the jail system.

The 18-year-old, named as Bourhan Hraichie, has been charged with causing grievous bodily harm and intentional choking following the incident after lockdown at the medium-security Kempsey prison north of Sydney last week.

He reportedly assaulted his cellmate then used a razor blade to carve "e4e" into his head, an apparent reference to the Islamic State group's "eye for an eye" mantra, before placing a towel on his face and pouring boiling water over him.
