Riccardo Accaputo was watching TV with his aunt on Wednesday night when up to eight men stormed their home in Melbourne's west armed with weapons.

A group of between six and eight men broke into the Gillespie Drive house in Melton South just after 7pm, police say.

One of the men demanded the keys to Mr Accaputo's Ford XR8 sedan parked out the front, while the others ransacked the house.

Armed with metal poles, the men stole cash, computers and jewellery from the terrified pair.
