Nine police dogs to target wild WA parties

Nine extra police dogs have been recruited to the K9 unit to help West Australian police break-up out-of-control parties.

Police Minister Liza Harvey said the police kennels had also been upgraded to accommodate the new canines.

"Police tell me it's quite remarkable the effect one of these dogs can have on an unruly mob," she said.

"They may abuse officers, but quickly quieten down when a police dog lunges towards them."

So far, 98 people have been charged with out-of-control gathering offences since the legislation was passed, and the courts have ordered more than $37,000 be repaid to police for the cost of breaking-up the crowds.

"The message is getting through to parents that if their child hosts a party which is splashed all over the internet and it gets out-of-control, it's going to cost them a lot of money," Ms Harvey said.

The K9 boost is in addition to providing police with two new riot trucks equipped with shields, helmets, portable video scanning units and computer equipment.
