THE window of a police car was broken and beer bottles smashed in the street as a 16th birthday party in Cudgen attended by about 200 youths turned sour on Saturday night.
One police car team from Kingscliff attended the scene in John Robb Way after neighbours phoned police to complain about noise from the huge gathering at 9.30pm (NSW).
Police called on back-up support to quell the unruly crowd and police-car crews and highway patrolmen were called to lend assistance from Tweed Heads, Murwillumbah, Brunswick Heads and Byron Bay.
Tweed Heads Inspector Jim Kain said there was a lot of noise and broken bottles in the street, but no-one was injured.
He said the youths, aged 14 to 20, had apparently turned up at the birthday party.
No-one was arrested, although police gave move-on directions for breaches of the peace and issued traffic infringement notices.
The big crowd was dispersed by about 10.45pm, after the rear window of a Tweed Heads detectives' unmarked car had been smashed.
Inspector Kain said it was the second consecutive weekend of rowdy street parties in the Kingscliff area.
The wild street scene in Cudgen came just 24 hours after a similar, larger disturbance outside a house on the Gold Coast last Friday night.
An Ashmore family was assaulted and their car and house vandalised when a crowd among 300 revellers gatecrashing a party next door turned nasty.
Police said family members returning to the Hillview Parade home were mobbed after the party spilled onto the street.
A 48-year-old father and his 21-year-old son were punched.
The partygoers smashed windows in the house and threw rocks at the family's car.
