Men brandishing "edged weapons" and metal poles broke into a family home in Melbourne's north overnight, attacking one man and stealing a BMW in what is believed to be the latest episode in a violent two-day city-wide crime spree.
The armed gang broke into the home in Avoca Avenue, Mernda, about 4am on Tuesday, leaving a 41-year-old man with minor facial injuries. A 40-year-old woman and two children who had been asleep in the home were not hurt.
The thieves dumped the Hyundai i30, stealing a 2010 grey Mercedes sedan and a black 2015 Honda HR-V.
No arrests have been made.
Inspector Pannell said police hoped to make quick arrests.
"We suspect it's the same crew," he said.
He said the thieves appeared to be using and dumping the "high-end performance ... nice cars", as opposed to selling them.
