Vic house fires suspicious

Suspicious fires in neighbouring Melbourne homes which happened within days of each other are being investigated.

Fire crews were called to a house fire in Broadmeadows early on Friday.

The fire extensively damaged the home and is being treated as suspicious.

The house next door caught fire on Sunday morning, causing damage to one room and is also being treated as suspicious.

A Victoria Police spokeswoman said both fires were being investigated but it was too early to say if there was a connection.
