A 14-year-old boy was hit with a metal bar during an attempted robbery in Marsh Farm.
The teen was approached by two men wearing balaclavas at the junction of Northwell Drive and Lygetun Drive at 7.20pm on September 22.
He tried to walk away but one of the men struck him on the leg with an iron bar, causing him to fall to the floor.
They punched him in the face, stamped on him several times and then started patting him down.
The boy managed to strike one of the offenders before running away and raising the alarm.
One of the men spoke with a strong Irish accent and was of a large build.
The second was smaller, with a skinny build.
