Four people are still being questioned by Gardai in Dublin following a stabbing incident in the south inner city yesterday afternoon.

Three men and a woman were arrested after a man was stabbed several times in the face in the Maryland area of the Coombe at around 3pm.

His injuries are not though to be life-threatening.

Reports this morning say one of those in custody is a notorious gangland boss who is involved in a bloody feud with a rival drug dealer in the Crumlin/Drimnagh area.

Thirteen people have died as a result of the feud in recent years.
