A convicted robber escaped from Sudbury Prison this morning.

Police officers, dogs and a helicopter are involved in the search for Joseph Powell, who ran off across fields at 9am.

It is believe he is in Foston or Hatton.

The 27-year-old is black, 5ft 10in tall and wearing a black t-shirt and black three-quarter-length trousers.

Powell comes from Manchester and is serving a life sentence for robbery.

Anyone who sees a man of that description should not approach him but contact the police immediately on 999.
