Police are appealing for witnesses after a teenager had his phone stolen in a robbery.

Huddersfield CID want to speak to anyone who witnessed or has information about the offence which took place between 7.55pm and 8pm on St Johns Road, Birkenshaw on Thursday.

The incident happened after the victim, a 19-year-old local man, was approached by a man while walking in an unlit ginnel.

As he walked past, the man assaulted the teenager and demanded his Sony Xperia S mobile phone, which had fallen to the ground. The attacker picked up the phone and ran off, leaving the victim with superficial facial injuries.

The suspect is described as white, in his early 20s and wearing a dark coloured top possibly with the hood up.

Anyone who has information can contact Det Con Divek Singh Ubhi at Huddersfield CID on 101 or Crimestoppers on 0800 555111.
