A GUN wielding robber forced his way into a bookmaker's shop, but got away with a mere £100 after dropping most of his ill-gotten gains on the way out.

The incident happened on Monday at William Hill in the High Street, Watford, at 10.15am.

The offender forced the deputy manager to empty cash from the tills and forced him to wait inside the staff toilets.

The offender then made off towards Lower High Street. He is described as white, aged 35, 5ft 11inches tall and wore a dark coloured jacket with light stripes on the arms, a black woollen hat, black gloves and large sunglasses.
