They say there have been 40 burglaries in New York and New Jersey since 2009 that fit the group's pattern - most of them in the last six months.
The break-in artists are known to stalk wealthy neighborhoods, sometimes in rented luxury cars. They ransack homes for cash and jewelry and leave in two minutes - sometimes with $50,000 to $100,000 in proceeds.
Three alleged members were arrested in Somerset County last week.
Detectives tell The Record newspaper they are trying to determine whether the recent break-ins are the work of the notorious James Bond Gang that terrorized northern New Jersey and New York 20 years ago - or copycats.
