BALTIMORE — Federal and local authorities have charged three people following an investigation into a Baltimore gun distribution ring.

The Baltimore Sun reports they also seized weapons, cash and drugs with a street value of roughly $30,000.

Baltimore Police spokesman Detective Donny Moses said the suspects were expected to face federal charges, but the U.S. Attorney’s office had not released those charges by late Thursday.

Sixteen guns were seized, along with two ounces of heroin, two bullet-proof vests and $8,000, when officials executed five search and seizure warrants Thursday. The searches took place across Baltimore and in western Baltimore County.

Moses said the case began in January when a man arrested on a hand gun charge began cooperating with police.

He said police have not yet determined where the guns originated.
