Police are hunting a teenager who killed a duck with a catapult.

A witness saw three boys walking away with a dead duck after they fired at birds by the watercourse near Guy Road in Wallington on Saturday afternoon.

Officers arrived and searched the area, but were unable to find the teens.

Police spoke to two boys near the area as they continued their enquiries at about 3pm yesterday but no arrests have been made.

A spokesman for Sutton police said officers were patrolling the area.
