Police are considering whether to charge the parents of a 16-year-old boy whose Gold Coast party was gate crashed on the weekend by hundreds of teenagers after it was promoted on Facebook.
Charges may also be laid against the people who provided the venue at an industrial estate at Ashmore if investigations show they broke the conditions of their liquor licence and provided alcohol to underage teens.
Acting Superintendent Glenn Allen said the parents and the providers of the venue bear some liability for what happened.
"Part of our investigation will focus on that," he told reporters on Monday.
One person was arrested for obstructing police and a number of liquor infringement notices were issued after police were called in to control an unruly crown of about 600 teenagers.
"There were about 200 invited guests but another 400 turned up after the party was posted on social media," he told reporters.
Supt Allen said police were faced with a difficult situation with the teenagers gripped by "mob mentality" and running riot near a busy road close to a residential area.
"As you can imagine a lot of those teenagers were not well mannered and some were affected by alcohol," he said.
"We were concerned for surrounding residential areas as often these things can escalate and kids can go away and damage fences, letter boxes, we've seen it before."
Supt Allen said officers handled the situation very well with no reports of damage to property in surrounding areas.
He advised parents planning parties for their children to make sure the events were not posted on social media, and to register their event with the police "Party Safe" service so regular patrols could be arranged on the night to defuse potential problems before they got out of hand.
