Police officers investigating a robbery where a cashier was threatened with a knife are appealing for witnesses and information.

The robbery took place at the Jet Garage on Sutton Road in Hull on Friday 17 February.

At 6am a man, described as white, of slim build in his mid-20s, wearing a high-viz jacket, grey bobble hat and a grey scarf covering his face, entered the petrol station and walked behind the cashier desk.

He threatened the cashier with a knife, demanded money, and £200 in cash.

The offender fled the scene and the cashier was not physically harmed but was left very shaken.

Humberside Police is appealing for anyone who saw anyone acting suspiciously or that may have seen anything that would assist with enquiries to call its non-emergency number 101 quoting log 76 of 17 February.
