Police search for man 'involved in police chase' in south-western Sydney

Police are searching for a man earlier involved in a police chase who then barricaded himself inside a townhouse at Liverpool in Sydney's south-west.

Dozens of heavily armed police entered the townhouse on Roland Avenue but he was not inside.

The man was involved in the pursuit about midday and refused to stop, police said.

The man then jumped out of the car, ran into the townhouse and police believed he locked himself inside.

A number of police and members of the tactical response group were at the scene.
