Gun thieves may be cold-calling collectors in a bid to find out whether they are at home.
Police today issued a warning for firearms collectors to be wary of suspicious calls, after a cache of 15 high-powered firearms was stolen from the home of a collector in Dargaville, Northland.
Detectives investigating the case have become aware of several recent occasions where gun enthusiasts and collectors have received phone calls which appeared to be an attempt to identify whether or not they were at home.
In some cases, the caller has hung up without saying anything.
Police are investigating the calls as part of the wider probe into the theft, and are calling for more information from collectors.
