Teens armed with knives robbed people in a suburban street in Melbourne's west on Friday night after police broke up a gathering of up to 200 teenagers at a property rented by a 15-year-old boy through Airbnb, police allege.

The owner of the Point Cook property called Triple-0 after the party, which had been advertised on Facebook, sparked noise complaints and spilled out onto St Clair Avenue about 8.45pm Friday, before a violent crime spree ensued.

The property was not damaged but it's believed some of those in attendance, aged between 14 and 16, remained in the area after police attended.

Police say two teens were approached at 10.45pm by five youths on the same street. Demands were allegedly made for their belongings before a knife was produced.

"The offenders assaulted the two teenage males and stole a mobile phone, backpack and pair of shoes," a police spokesman said.

"The victims were treated at the scene for minor injuries and did not go to hospital."

A short time later two other teenage males were robbed and assaulted by a group of about eight males on The Crescent.

"A 17-year-old was taken to hospital with minor injuries," the spokesman said.

"The offenders in both robberies are perceived to be of African appearance.

"Police are investigating whether the incidents are linked."

Senior police declined to speak to The Age or answer questions about the incidents when asked on Saturday.

Other officers were told not to speak to the press about what occurred.

An Airbnb spokesman said the boy who rented the property had since been banned from using the short-stay rental site. Thecompany maintains, though, that such incidents are rare.

Airbnb users are meant to be aged 18 years or older.

"Building a safe, trusted community is our number one priority. We have permanently banned this individual from our platform," they said.

"There have been over 400 million guest arrivals in Airbnb listings to date and negative incidents like this are incredibly rare."

The incidents come as police investigate a string of other Airbnb parties, some rented using stolen credit cards, including at high-rise CBD apartments.

Last Sunday, residents in a city apartment complex were woken by knocking on their doors and a men checking door handles. Two apartments on two different floors were broken into while the occupants were sleeping inside.

It’s believed up to three men staying in a short-term rental in the Spencer Street complex were behind the home invasions. CCTV footage captured them leaving with their hands full of other people's belongings.

Acting Assistant Commissioner Tim Hansen said aggravated burglaries linked to short-stay apartments were an emerging crime trend.
