It comes amid another series of arrests at the weekend.

The NSW Bureau of Crime Statistics and Research (BOCSAR) has compiled figures for Wagga that show prohibited and regulated weapons offences have jumped almost 20 per cent per year since 2009.

The figures show that from 2009 to September 2014, the instances of firearms offences in the Wagga local government area has risen from 184 to 364, calculated by the rate per 100,000 people.

Junee is also in the midst of a record five-year high for firearm offences.

Elsewhere in the Riverina, the crime statistics show Griffith has almost doubled its rate of weapons offences in five years.

Cootamundra police said at the weekend three men were arrested and charged over a serious theft of firearms.

Police arrested a 24-year-old and a 19-year-old for stealing seven rifles and two shotguns.

It is alleged the pair broke into a shed on a property and used the keys to steal the weapons from the gun safe.

But it was some time later that police were able to locate the weapons.

Police said a call out to a domestic violence incident lead them to the stack of weapons and the arrest of another 38-year-old man, who was in possession of one of the stolen weapons.

With new information, police were able to track down the original thieves and five of the nine weapons – the others have not been recovered and remain at large.

All three men have been charged with firearms and break and enter offences and will front court at a later date.

The Cootamundra arrests come hot on the heels of an arrest in Wagga last week.

Bail was refused on Friday for an alleged outlaw motorcycle gang member accused of possessing a revolving rifle in defiance of a firearm prohibition order against him stretching back 25 years.

Police brought Anthony Charles Debnam, 46, to court after executing a search warrant at his Kooringal home, where a .357 revolving rifle allegedly found hidden in a stereo speaker.
