Concerned parents have spoken of their distress after footage emerged of a man restraining a young boy as other youngsters lined up to hit him.

The sickening incident, caught on camera and circulated widely on social media, occurred just outside the gates of Lliswerry High School in Newport, Wales on Wednesday afternoon.

Two people have now been arrested in connection with the alleged assault, Gwent Police has confirmed.

Horrifying footage of the incident shows a young boy looking anxious as he is approached by a man and two other boys.

The man can then be seen grabbing on to the youngster's shoulder and appears to speak to the two boys, before nodding towards the victim.
