NEW BRITAIN – A city man arrested by state police last month and accused of trafficking firearms from his New Britain home, where authorities found more than 100 guns and a 3D printer they believe was used to make many of the firearms, is expected to face additional charges.

Steven Mastrianni, 39, of 37 Hillhurst Ave., was scheduled to be arraigned Tuesday in New Britain Superior Court, where prosecutors indicated he will be served with an additional arrest warrant when he appears in court on June 7. No additional information was provided about the additional charges expected.

The warrant from Mastrianni’s original arrest, meanwhile, remains sealed. 

The 39-year-old remains held on $500,000 bond and has not entered a plea to 19 counts of sale of large capacity magazines, nine counts each of weapon in a motor vehicle, illegal transfer of a long gun, sale of an assault weapon, illegal transfer of a manufactured firearm without a serial number and a single count each of firearms trafficking and possession of an assault weapon.

The charges stem from a raid at Mastrianni’s home on April 12, when state police reported finding more than 100 guns and three homemade explosive devices. The search was conducted following a 10-month investigation. The explosive devices were safely disposed of by the Connecticut State Police Bomb Squad. 

State police said a vast majority of the weapons were considered ghost guns, which authorities believe were made using a 3D printer that was seized from the home of Mastrianni. A ghost gun is made without a serial number and is untraceable for law enforcement.

At the time of his arrest, state police said, Mastrianni was a pistol permit holder who had a ghost gun on his person.

According to investigators, authorities raided Mastrianni’s home, as well as several of his vehicles. More than 150 evidence items were seized, including about 125 guns, as well as components used to make firearms fully automatic. The firearms that were seized included shotguns, pistols, fully-automatic guns, semi-automatic guns, pistols with threaded barrels. Also seized were hundreds of high-capacity magazines and tens of thousands of rounds of ammunition.
