Two teenagers have been arrested after shocking footage emerged online of a boy being attacked by a gang of thugs in an east London park.

The video shows the alleged victim being surrounded by a group of boys before he is knocked to the ground by a violent blow to the head in Raphael Park, Romford.

Before he is punched, he is stood talking on a mobile phone on speaker as the other boys listen and one mentions “getting money tonight”.

One of the group can be heard saying: “you knocked him out bruv”, while another tells them not to kick him and to leave him lying on the ground.

The alleged victim then staggers to his feet before he is flattened by another blow to the head.

He lies on the floor sobbing, while one of the boys says: “Why are you crying on the floor bruv?”

The boy is then kicked in the side before the video ends.

He was taken to hospital for treatment after the attack but has since been discharged, police said.

Met Police said in a statement today that two boys, both aged 17, were arrested on Sunday and Monday in connection with the assault.

Both have been bailed to attend an east London police station in late November.

Officers are appealing for anyone who has information about the attack on July 21 to come forward.

Anyone with information can contact police via 101 or Crimestoppers anonymously on 0800 555111.
