NASHUA — Police have arrested a 22-year-old man on forgery and weapons charges following a burglary in the city.

Seth Stephens, 22, of Nashua was arrested Friday in the culmination of an investigation that began Sept. 25, when several personal checks were stolen in a break-in at a downtown residence.

Detectives traced one of the checks after it was cashed at an area bank and said Stephens was the person who cashed the check. Stephens was arrested on a warrant, and police said they found him in possession of a butterfly-style folding knife.

He has a previous conviction for theft and was charged with being a felon in possession of a dangerous weapon in addition to a forgery complaint. Both charges are felonies.

Stephens was held at the Nashua police station on $10,000 bond and will be arraigned today in 9th Circuit Court in Nashua.
