THREE people have been arrested after an out-of-control party in western Sydney left a wave of destruction across three streets with cars rolled over by hordes of roaming teens.

Police swarmed Fulton Ave, Wentworthville and surrounding streets after receiving triple-0 calls from residents watching their streets descend into mayhem.

Cars were flipped upside down and had their windows smashed and mirrors broken off after the party, which was believed to have been posted on Facebook, got out of hand.

The party started about 8.30pm on May St, Constitution Hill, about 2km from Fulton Ave.

"I was in the backyard renovating and I heard voices coming up the street so I went upstairs to look out and saw kids flipping my car over,'' Eric Palowski, 40, said. "They were screaming and swearing. I thought it was a fight at first.''

Police made their way through the neighbourhood door knocking shocked residents about the damage done to their cars.

Anil Chandy, 46, said his nephew's windscreen had been smashed, but was only made aware when police knocked on his door at midnight.

"I heard people making lots of noise and banging but I didn't expect this," the Railway St resident said.

His family stood next to him on the street inspecting the damage and were in disbelief when informed of the damage done to the whole neighbourhood.

"Facebook strikes again,'' one police officer said as he walked up the street searching for more damage.

Paramedics attended to a 17-year-old boy with injuries to his face as the chaos spread across Wentworthville.

Other youths in cars were seen driving through the area, laughing at the damage caused.

A NSW Police spokeswoman said police dispersed a number of young people "who were all over" Wentworthville, including near the train station.

Last night, revellers flooded Facebook with messages about the "round six" party a free house party in Wentworthville.

One user, near Westmead, said: "Multiple windows smashed, 2 flipped cars and crazy fights, and the nights just started."

Police arrested three juvenile males who were taken to Parramatta Police Station.

A 17-year-old was charged with affray, offensive conduct and breach of bail.

The second teen, aged 16, was charged with affray, offensive behaviour, resist arrest and breach of bail.

The third male, also aged 16, was released pending further inquiries.

The two juveniles were refused bail and are expected to appear at Parramatta Children’s Court today.
