HI-TECH thieves with metal detectors and industrial grinders are hitting homes in Sydney's wealthy suburbs, searching out hidden wall safes then ransacking them.
Residents said up to 45 homes from Wahroonga to St Ives were targeted by the well-organised crews over the past few months.
The gang or gangs break into houses during daylight hours and rob safes of expensive jewellery and in some cases cash. More than $50,000 was netted in one robbery.
Police yesterday confirmed a specialist taskforce has been set up to investigate the robberies, which all appear to have been carried out in a similar fashion.
"There have been numerous incidents in the area which appear to be related, yes, and we've got some officers designated to looking into that," a police spokesman said.
One victim said police had told him they believed the gang was using metal detectors to locate safes hidden behind walls or other items within houses.
Once the safe has been located, the thieves then grind off the doors to gain access to the valuables.
"They [the police] are also looking at the possibility there are two different gangs of thieves," the victim said.
"In some cases people are finding their homes in disarray, the safe door grinded off and a lot of damage done to the house."
While police try to tackle the elusive gang, one St Ives local has taken matters into his own hands, distributing an anonymous flyer in letterboxes warning people of the spate of thefts.
The letter details how the writer's family fell victim to the gang, arriving home to find their home ransacked and the safe emptied.
"Beware of this," the anonymous letter says.
"Someone must know something, or must have seen something."
A canvass of the suburb, and those close by, revealed up to 45 homes had been targeted in a similar fashion since March this year.
While not all homes had had safes targeted, the method of entry was similar, with thieves forcing window locks in the majority of cases.
