SYDNEY - At least four people were wounded, including a bishop, in a knife attack during a service at a church in a suburb of Sydney on Monday, police and witnesses said, triggering clashes between angry residents and police.

Police said they arrested a 15-year-old male at the scene and were forced to hold him at the church in Wakeley, a suburb about 30 km west of downtown Sydney, for his own safety after a crowd gathered outside and demanded the attacker be brought out.

It was the second major stabbing attack in just three days after six people were killed in a knife attack at a beachside mall in the Bondi area.
