A Saugus police officer allegedly caught on surveillance video stealing a gun has resigned.

Chief Domenic DiMella tells The Daily Item of Lynn that officer Jason LaBella sent him a one-sentence letter of resignation on Thursday.

LaBella, an Army veteran who has been a patrolman for less than two years, is facing a criminal larceny charge after he was allegedly caught on video tape stealing a handgun from a member of the Massachusetts Rifle Association, a Woburn-based gun club.

DiMella says LaBella was given the option of resigning or being fired.

Woburn police say a member of the gun club contacted them Jan. 22 after noticing a 9-millimeter Smith & Wesson handgun with five bullets inside was missing from a firing range.
