Thousands of pounds have been raised for an anti-bullying charity after a video showing a violent assault on a 15-year-old boy in a park went viral.

A shocking video was shared on social media on Monday showing a boy being floored after being hit on the head and kicked on the ground in a wood by a group of boys,

At the end of the clip, the boys leave the victim on the ground and make off with his phone.

A Go Fund Me page has been set up for the victim of the assault and nearly £3,500 have been raised.

The fundraising page set up by the Facebook page Bradford Boyz initially aimed to raise £800 for the victim to buy a new phone, but within a few hours the target was smashed.

The additional money will be donated to an anti-bullying charity.
