Three more teenagers have been arrested after a 17-year-old was stabbed in the buttocks.

Police arrested a 16-year-old boy after attending to the victim of a stab wound to the lower right buttock on Varley Road, Custom House on Monday.

Officers arrested two 15-year-old boys and a 16-year-old boy yesterday for grievous bodily harm and they have all been bailed to re-appear at an east London police station.

The teen was found lying on the ground being tended to by members of the public after he was chased by a group of 10 to 15 males who also stole his mobile phone.

The victim also suffered bruising above his left eye and grazing to the right side of his head but he discharged himself from the Royal London Hospital later that day.
