A Dorchester man already being tracked as a suspected arsonist was arrested Monday on charges he set a Roslindale house on fire early Monday morning, federal and city officials say.

Jose Baez, 38, was arrested after a GPS unit surreptitiously placed on his care tracked him to the area of 11 Firth Rd., where a fire that broke out early this morning sent one resident to the hospital and caused an estimated $100,000, according to statements from the US Attorney's office in Boston and the Boston Fire Department.

He was arrested on a federal charge of arson of property. Officials say they are looking at Baez's possible connection to a string of arson fires across Boston since 2008.

According to a statement by the US Attorney's office:

"At 3:21 a.m. this morning, the GPS notified law enforcement that Baez's vehicle had left his residence and was stationary on Bexley Road in Roslindale for approximately 15 minutes and then moved to 140 Columbia Road where it remained parked. Bexley Road runs parallel with Firth Road and is a short distance away. According to the complaint, officers approached Baez who exited the vehicle and officers immediately noticed a strong odor consistent with that of gasoline, and Baez was subsequently arrested."

If convicted, Baez could get up to 40 years in prison and a $250,000 fine.
