A sixteen-year-old girl was robbed at knife point of her mobile phone by two men in the early hours of today.

Detective Inspector Ian Thornes of Huddersfield CID said the incident occurred some time between 1.30am and 1.45am at the junction of Birkby Hall Road and Crescent Road, Birkby.

He said the victim was waiting for a taxi when she was approached by two Asian men. One of them told her to give him the Samsung Galaxy S4 phone and she handed it over.

When they realised it needed a password he produced a silver-bladed, knife, three inches long and demanded she give them the code.

The man said: "Don't scream as we walk off".

Det Insp Thornes said the victim got in a taxi and went to a friend's house and the friend called the police.

Descriptions of the men are as follows: the first was 5ft 10, very slim, clean shaven and aged 18-19-years-old and was wearing a grey Puffa jacket with black gloves.

The second was 5ft 7/5ft 8, fat, 20, and was wearing a blue hooded top. He had stubble on his face.

Anyone who can help should phone the police on 101 and ask for PC Nicole Senior.
