A gun shop in Grass Valley was burglarized Wednesday, one of a series of break-ins at stores in Northern California that carry weapons.
The burglary occurred about 8 a.m. at Mustang Firearms, 10893 Alta St., when two masked men forced their way through the front door and took firearms from display cases.
The burglars, who also wore gloves, took about 20 handguns. The intruders spent a short time in the store before leaving in a late model gun-metal gray Nissan Juke sport-utility vehicle with paper dealer plates.
Last month, authorities from the Bureau of Alcohol, Tobacco, Firearms and Explosives made arrests and found the vehicle used in connection with burglaries of gun shops in Rocklin and Folsom.
The incidents added to a growing trend of such burglaries in the greater Sacramento area. At least 12 similar incidents have taken place in the area the past six months, resulting in between 230 and 240 firearms being taken, federal authorities said.
