A man suspected of leaving a burning propane tank next to a Boston squad car last week was taken into custody after an investigation into the incident, police said on Sunday.
Asim Kieta, 42, of Dorchester, was arrested late on Saturday in the city's Charlestown section and charged with possession of an explosive device, arson and assault with intent to murder, among other counts.
Members of the Boston police bomb squad responded on Friday to a report that a parked police cruiser in South Boston had been damaged by an incendiary device, described by a spokeswoman as a propane tank.
When they arrived, officers found the damaged car with evidence of an explosive device next to it, the Boston Police Department said in a statement on Sunday. The vehicle had been unoccupied.
