Three teenage girl bullies who filmed a vicious attack on a younger girl and put it on Snapchat have escaped with police warnings.

The vile trio violently punched and kicked 15-year-old Sophie Nevard after burning her hair extensions in front of a crowd.

A 10-second clip showed her cowering on the floor with her hands covering her face as the pair repeatedly kicked and punched her in a park.

A girl in the background can be heard shouting "stop stop stop" but another mockingly says: "Look at her weave."

The video was shared on Snapchat with the caption 'Sophie Nevard getting f***ed up' and smiley face emoticons.

It was seen by Sophie's horrified mother Sarah who put it on Facebook in the hope of catching the girl bullies.

Police were alerted and a 16 and 17-year-old girl have now received cautions for assault and a 15-year-old girl has been given a harassment warning.

A friend said Sophie had been left too scared to go out after the attack on July 11 in Hesketh Park in Dartford.

She posted: "Here's one vid of my friends sis and what happened absolute tramps bully and beating a 15yr old there 20 ffs and it started from behind."

When she posted the video on her Facebook page Sarah, 36, wrote: "These two girls one aged 18 had beaten up my 15 year old daughter and filmed it.

"Humiliating her by burning her hair extensions and laughing about it on snapchat. Absolutely fuming."
