Police are investigating following an attempted armed robbery at Gosford this morning.

About 6.20am (Thursday 19 February 2016), three people armed with a baseball bat, broom handle and knife, approached two employees of a hotel on Mann Street, as they were walking through a car park at the rear of the premises.

Police have been told the trio threatened the employees, before a man armed with a baseball bat assaulted one of them.

The armed group then entered the hotel and threatened a third employee, before leaving the scene empty handed.

The trio was last seen jumping a fence at the side of the premises and are believed to have driven from the scene in a white ute, north along Hill Street.

The injured employee was taken to Gosford Hospital as a precaution; however he has since been released.

Officers attached to Brisbane Water Local Area Command were called and established a crime scene.

As inquiries continue, police are appealing for any witnesses, or anyone with information, to come forward and contact Crime Stoppers.
