A postmistress was threatened with a knife after armed robbers burst into a quiet village post office.

The three-strong gang fled with an undisclosed quantity of cash after the raid at Castle Rising Post Office yesterday afternoon, Tuesday January 30th.

Police say three offenders, all wearing scarves around their faces and at least one armed with a knife, entered the Lynn Road premises at 4.10pm and threatened the post mistress, demanding money.

Neither the post mistress nor another man present in the store was injured although both were left extremely shaken.

The men left the scene in a dark coloured saloon car, believed to be a Vauxhall Vectra or Astra and possibly driven by a fourth accomplice.

A man entered the Post Office just a few minutes before this incident asking for details on opening up and account. He may be an important witness and officers are asking for him to come forward.

Witnesses to the robbery or the getaway car, or anyone seen in suspicious circumstances near the Post Office in the period leading up to the robbery is asked to contact Det Sgt Pete Jessop at King's Lynn CID on 0845 456
