A 16-year-old boy who was walking through Ipswich was approached by a group brandishing a knife demanding his phone and money.

The teenager was in Bloomfield Street, near to the junction with Spring Road at about 7.20pm on Wednesday.

A group of four teenagers - three males and one female - walked towards him and passed him in the pavement.

But when he turned around, two of males were behind him and one was holding a knife. The offender demanded his mobile phone but the victim did not have one, so gave him an amount of cash.

The two offenders ran off towards Freehold Road and the teenager was not injured from the incident.

The first offender, who was holding the knife, is described as white, with blue coloured eyes, between 16 to 19-years-old, about six-foot tall, of slim to muscular build.

He was wearing a black woollen hat, black scarf covering his face, black trousers and a black waterproof coat.

The second offender is described as wearing a black hat and coat.

The female is described as white, between 16 to 19-years-old and had brown coloured hair in a ponytail style. She is about five foot six inches tall with a stocky build. She was wearing a grey hooded top with a blue body warmer.

Anyone with information should call police on 101 or Crimestoppers on 0800 555 111.
