Woman bound during NSW club armed robbery

A woman's hands and feet have been bound with duct tape by two armed men who forced their way into a NSW Hunter region bowling club and fled with cash.

Armed with a shortened firearm and a sledgehammer, the men entered the Abermain Bowling and Recreation Club on Monday night, tying up the employee before stealing cash and ransacking the premises, police said.

The pair fled in a Nissan Pulsar which was found nearby and burnt out several hours later, police say.
