FOUR gatecrashers kicked in the front door of a Cranbourne house where an 18th birthday party had just finished.
The four males entered the house on Wentworth Street about 1.35am on 20 June, one armed with an iron bar, while another waited by a white Holden Commodore station wagon parked outside the house.
Two of the males were refused entry to the party earlier in the night.
Police said the gatecrashers demanded to know the whereabouts of a person and they left in the car a short time later.
One of the males was described as tall, about 20 years old with blond hair and acne.
Anyone with information can contact Crime Stoppers on 1800 333 000.
