Home invaders steal Biskit the American Staffy during violent home invasion, robbery at Pooraka A POORAKA man who was tied up at knifepoint and robbed in a violent home invasion wants just one thing - his four-legged best mate back. Resident Mark, who did not want to use his surname, said three men broke into his Duffield Drive home about 1.30am. "I had a light in my face and a knife to my throat the whole time and they were saying "keep your eyes shut, if you open your eyes we're going to kill you," so I just tried to do what they wanted," he said. Mark said after the men fled with his wallet, keys phone and necklace, he was shocked to find they had also taken his eight-year old American Staffordshire terrier, Biskit. "He means the world to me, I've had him about seven or eight years since he was a pup," he said. He cost me $600, but he's worth $600 million to me, he's worth a fortune to me. Mark said he had no idea who the intruders were or why they targeted his home, and that his main concern was Biskit's welfare. "The pound have known for hours and hours and they haven't rung back so nobody has picked up the dog, which is not a good thing, because obviously he's behind a fence somewhere," he said. I don't care about the jewellery or Play Stations or stuff like that, I just want my dog back. One suspect was described as being aged about 40, with a slim build, dark complexion and wearing a blue hooded top. Police are investigating whether the same men were responsible for another home invasion and robbery at Greenwith about two hours earlier. Detective Senior Sergeant Mick Clarke said police did not believe either incident was gang-related, but they were likely to be targeted attacks. "We are investigating them both together and we are establishing whether there are any links between the two incidents," he said. He said it was unusual for a dog to be stolen and was "guessing" the dog knew the suspects. In the Greenwith home invasion, three armed men forced their way into the Cromer Court home about 11.30pm, terrorising the occupants with a handgun, machete and crowbar. The offenders forced entry when a man answered the front door. Three men wearing Halloween-style masks forced their way into the house, using the gun to make threats and demand money before fleeing with a phone, car keys and a purse.
