A man who allegedly kept police at bay from inside a Sydney townhouse after leading them on a wild pursuit through the city's west, faced Liverpool Local Court today on a range of firearm and driving charges.

Marko Krivosic has been charged with possessing unauthorised firearms, possession of ammunition and driving while disqualified.

He was arrested around 8am following a foot pursuit on Speed Street, Liverpool.

Detectives from the Firearms Investigation Squad and Strike Force Crosswise arrived at a property on Bathurst Street, Liverpool around 6.30am yesterday.

Officers allegedly seized ammunition and a small bag containing an unknown white substance, before moving on to a property on Lehmann Avenue where they seized a shortened bolt-action shot-gun around 12.30pm.

Police then tracked down a silver Subaru Impreza sedan on Dale Street, after a police dog picked up a scent and followed it to a townhouse on Roland Street.

Police allege the man then locked himself inside the property.

Police, including officers from the Public Order and Riot Squad and the Tactical Unit, spent much of the afternoon surrounding the townhouse on Roland Street and forced entry around 4.30pm, however no one was found inside.

Earlier, police had attempted to stop the fugitive on nearby Lehmann Avenue before pursuing him through several streets to the house.

The Liverpool man was wanted over several driving offences.

Residents have told 9NEWS of their fright after seeing tactical police moving through their backyards and street.

Police negotiators initially attempted to speak with the man inside before police dogs and then officers were deployed.

On the property, investigators found a .44 calibre revolver and .22 calibre revolver, and approximately 150 rounds of ammunition, as well as around 49 grams of a crystal substance believed to be methamphetamine (ice).

Police also seized two vehicles.
