COBRAM police believe a serial armed and dangerous burglar is on the loose in the town.
They believe the burglar, who stabbed a man who disturbed him two weeks ago, has struck three times this week.
In one case, he crept into a house and ransacked it while a woman was sleeping in a bedroom.
Now police are urging Cobram residents to lock their houses at all times and consider extra security measures.
Detective Sen-Constable Jason Williams said a house in Young Street was burgled on Tuesday night and hit again on Wednesday night.
Houses in Bisogni Drive and Punt Road were raided the same night.
Sen-Contable Williams said residents of the Young Street and Bisogni Drive houses were not home but, at Punt Road, a woman was sleeping and had later woken to find her home ransacked.
Computers, personal items and jewellery were stolen in the raids.
The spree comes two weeks after Cobram father David Hyde was stabbed when he disturbed a burglar in his Dudley Park Lane house.
He, his wife and two friends had been watching Friday night football.
It’s also the second time a Punt Road house has been raided — two women found a man armed with a knife in their house on the night of July 27.
“We are now considering these offences as possibly linked to David Hyde’s assault,” Sen-Constable Williams said.
“Despite our best efforts, the person remains at large. We ask people to remain ultra vigilant.”
He said people could take extra precautions such as a wooden rod on window tracks and upgrades to deadlocks.
“Be extremely vigilant of anyone acting suspiciously and contact police immediately,” he said.
“Don’t wait to report it — we want to know at the time.”
Sen-Constable Williams said police were exploring “every forensic avenue” and increasing patrols.
He said anyone who knew the person responsible, even if he was family, should come forward because the offender could be mentally ill.
“We are at the start of the help process,” he said.
“It begins with an arrest but, that’s when we can help.”
