A teenage girl has been rugby tackled to the ground and robbed of her mobile phone by another teenage girl and two men in ski masks.

Detectives investigating the terrifying attack today issued an appeal for witnesses to come forward.

A computer-generated image has also been released by officers of a teenage girl they would like to speak to in connection with the robbery.

It took place between 9pm and 9.25pm on Thursday, February 6 on a footpath in Havelock Road, Gravesend.

The 19-year-old victim was walking home from college when she heard a noise behind her.

When she turned round she was met by a teenage girl who immediately tackled her to the ground.

While on the floor, two men arrived and began searching her coat and found a mobile phone.

After a brief tussle, they snatched the phone and all three suspects ran off in the direction of Mayfield Road. The victim suffered a minor cut to her mouth.

The female suspect has been described as white, between 15 and 16, about 5ft 2ins, with shoulder-length brown hair and a chubby face. She was wearing a dark coloured puffa-style jacket with a hood and diamond stitching.

Both of the men were white and wore ski masks and dark tracksuits.

DC Shaun Ravate said: "While incidents of this nature are thankfully few and far between in Gravesham, it was nonetheless a frightening experience for the victim.

"I would like to appeal to anyone who might recognise the person in this image or who might have information about this robbery, to contact me immediately."

Anyone with information is asked to phone DC Ravate on 01474 366081, quoting reference XY/704/14, or contact Kent Crimestoppers anonymously on 0800 555 111.
