Ten people, mostly teenagers, have been arrested over a series of aggravated carjackings, burglaries and car thefts which occurred on Halloween night in Melbourne's south-eastern suburbs.

Eleven properties were raided on Tuesday across Narre Warren, Narre Warren South, Cranbourne North, Hampton Park and Elwood.

Police are yet to reveal which suburbs the alleged crimes involving the teens relate to, but say the incidents occurred between October 29 and November 5.

The raids relate to a Halloween night crime spree during which five men allegedly threatened a young mother with a machete after ambushing her in the driveway of her home in the early hours of the morning.
