Police in British Columbia are trying to get to the bottom of a teenage house party that spiralled out of control and resulted in nearly $70,000 in damage.

On Saturday night, police were called to a party in Ladner, north of Vancouver, where they found some 200 teens partying.

One young partygoer described the chaotic scene as "nuts," saying he saw "some kid go down the stairs on a rocking horse."

Liquor was flowing freely, while fists were flying, and soon, things got out of hand.

"People were head butting walls and just throwing coffee tables around," said another youth who attended the party.

Meanwhile, the 13-year-old who was hosting the gathering at her father's vacant house, was unconscious.

Upon their arrival, police cleared the teens out of the house, and rushed the teenage hostess to hospital, where she was treated for alcohol poisoning.

At that point, officers noticed a few thousand dollars worth of damage.

A couple of hours later, police were called back to the same residence after hearing reports of a break-in. This time, the house had been trashed.

"After police left, we don't know who it was if it was the same kids or different people, that we don't know yet, came back in, and just kicked the house apart," Const. Rick Peeler of Delta police told CTV News.

No room was left untouched. Computer monitors had been thrown through windows, a large-screen television had been kicked in, furniture and electronics were ransacked, and the family car had been stolen.

The vehicle was later recovered in a nearby ditch.

The 13-year-old hostess was supposed to be staying at her mother's house that night. She told her mother she would be sleeping over at a friend's house, but instead went to her dad's house, while he was out of town on business.

The girl has reportedly told police she had planned only a small gathering for a few close friends.

While there have been no arrests so far, police are receiving help from angry parents.

"I'm not sure if anyone has called in to say their son or daughter did damage, that I don't know, but we have had parents bringing in their kids in to be interviewed," Peeler said.

Meanwhile, a community forum has been planned for Thursday night, said CTV's Vancouver Bureau Chief Todd Battis, adding that some 80 parents showed interest at first.

"That's ballooned to over 300 so they've had to move the event to a larger venue, and they're going to be talking about what led to this, how this type of thing could happen in the community."
