POLICE are appealing for a vital witness to help them crack a Milnsbridge robbery.

Two masked men entered a bookmakers shop on Market Street last Thursday at about 6.30pm.

They threatened the 28-year-old relief manager and snatched cash from behind the counter.

The first suspect is white, in his 20s, about 5ft 6in with a Yorkshire accent.

The second man is also white, aged about 20 and 5ft 11in tall.

Both wore dark hooded tops which concealed their faces.

Police want to speak to a woman, believed to be about 60, who told staff immediately after the incident she had seen two men acting suspiciously in the street but did not leave her details.

That witness or anyone else is asked to contact Pc Matt Walker on 01484 436659.
