More than a dozen youths of African appearance have gone on what police have described as a “horrendous” crime rampage in Melbourne’s west overnight.

Police released a statement on Friday, detailing a terrifying series of incidents they believe are all linked.

A 17-year-old boy was walking along Argyle Way, Taylors Hills, at 9.30pm on Thursday when a car drove past and stopped.

A male got out of the vehicle and demanded all the victims goods, the victim refused and kept walking.

The teenager was then struck to the back of the legs with what is believed to be a baseball bat.

He again ran, but was chased by the offender.

A second attacker then got out of the car. They pushed the victim to the ground, assaulted him and then dragged him along the ground before fleeing.

In a truly horrific incident, a 59-year-old woman was smacked on the face and forced to sit in the front room of her house while more than a dozen youths ransacked her home.

Police believe four males smashed the glass door of her Hillside home just before 11.30pm and entered.

Another 10 males then entered the home, stealing a number of electrical items and car keys.

“These are really horrendous offences. The community has every right to be outraged.” – Victoria Police commander Russell Barrett on 3AW.
