A knife-wielding robber demanded the keys to a hotel safe – but the staff refused to give them to him and he made off with only £30.

The balaclava-clad man entered the reception of the Aubrey Park Hotel, in Hemel Hempstead Road, Redbourn, at around 1.40am on January 3.

Despite holding a knife, staff refused to give in to the robber and he drove away in dark-coloured vehicle towards Redbourn Road.

The offender is described as white and of slim build, and was wearing black gloves, a balaclava, a long-sleeved top and shoes.

Anyone with information should call Hertfordshire Constabulary on 101.
