Details are scant but reports on social media suggest knives or a crow bar may have been the weapons in question although this aspect is unconfirmed.
A witness posted online: "I saw it, I was waiting to pick my son up. About 10 of them ran out of the street and started chasing a young lad from Cockburn, about 5 of them were kicking him, awful to see,but a van pulled up and a few guys got out to help him. I was going to go and see if he was okay but they ran off as the guys were going to chase them, poor kid, hope he's okay."
