A 13-YEAR-OLD gatecrasher allegedly raped a 15-year-old girl after slitting her throat at a party in Toowoomba, in southeast Queensland.

The defendant cried when he appeared in Toowoomba Children's Court yesterday charged with multiple offences.

Police allege he arrived uninvited to a house party in Harristown on Saturday night, before a fight broke out.



The 13-year-old was asked to leave but allegedly twice slashed his female victim's neck with a razor blade or knife.



It was alleged he then returned a short time later and raped the same girl.

He was charged with rape, deprivation of liberty and assault occasioning bodily harm while armed.

Toowoomba police said the girl was co-hosting a 16th birthday party for a friend at the time and there was no parental supervision.



The defendant did not apply for bail yesterday while his mother and grandmother watched proceedings.

His case was set down for committal mention on May 27 in the same court.

Police requested DNA samples and disease test results from the boy.

He remains in custody.
