UPDATE: Police are working to identify four armed men involved in a concerning home invasion in Lavington. Officers were alerted to the incident in the early hours of Tuesday morning. Investigators have been told the four men, who were armed with machetes and knives, forced entry to a home on Daly Street about 2am . A 19-year-old woman and 17-year-old boy were inside when the rear door was kicked in. The boy was threatened with a knife but wasn't injured. The group stole cash, mobile phones and a white Holden Astra, which they drove from the scene. The Holden was recovered about six hours after the incident, near Racecourse Road, with Victorian plates. Detective Acting Inspector Scott Trewhella on Thursday urged people to come forward with information to identify the four involved. "It's a significant concern to us when people are in the safety of their own homes and have someone force entry," he said. "Particularly whilst armed and taking property, which is why we are appealing to the public for information which may assist us." The detective said the victims weren't harmed. "In all the circumstances, they're travelling okay, obviously fairly shaken up," he said. It's unclear what the motive was or why the home was targeted. The vehicle has been forensically tested but other items haven't been found. Anyone with information can call (02) 6023 9299 or 1800 333 000.
