Four people injured in baseball bat attack at Perth auction FOUR men were injured when a group of masked men stormed a Perth auction today armed with baseball bats and hammers. Police were called to the Manheim Auction yard on Grogan Rd, near Perth Airport, about 11.20am. A Police spokeswoman said the attackers had their faces covered when they entered the auction and began assaulting three men. It is believed the two groups are known to each other. A fourth man was assaulted when he tried to step in and suffered lacerations to his head and a possible fractured shoulder blade. The masked bandits fled the scene in a silver car, possibly a 2006 Mazda 3, with no number plates. They are described as being about 183cms tall, olive skinned, wearing dark clothing. The four victims were taken to hospital, including a 47-year-old man, who is believed to have a broken nose caused by a screwdriver. A spokesman for Manheim Auctions confirmed there had been an "incident" but declined to comment.
