Masked men raid Sydney cigarette van

Police have set up road blocks in Sydney's west after the robbery of a cigarette delivery van this morning.

Four men wearing balaclavas threatened the driver at Guildford just before 9:00am (AEST).

They loaded the cigarettes into a white van before driving off.

Police say no weapons were drawn during the robbery and the driver was not harmed.

The road blocks have been set up around the robbery scene while police canvass the area.
