Police hunt machete-wielding pub robbers

A pub employee has been left shaken after being threatened with an axe and a machete during a late-night robbery in Sydney's innerwest.

Three masked-men burst into Petersham Public House and demanded cash from staff members just after 11pm on Tuesday.

The men fled in a waiting dark-coloured Subaru station wagon with cash, police said.

Duty Officer Mark George said the pub workers were shaken by the robbery.

"Thankfully no one's hurt but it's definitely a very serious offence that we're keen to get to the bottom of and solve promptly," Mr George told ABC News.
