ACT police raided a house on Throssell Street in Curtin yesterday, after a pizza delivery man was threatened with what appeared to be a handgun at 11.15pm on Saturday night.

The street was closed for a short time as police executed a search warrant relating to the incident involving a Domino's delivery driver.

An ACT Policing spokesman said a man was assisting police with their inquiries.

The investigation is ongoing. Larissa Nicholson
