The Boston Police Department reports arresting a man they say went on a bit of an arson early Labor Day morning that ended only when a resident spotted him trying to set a pile of stuff on fire in the resident's backyard and a police dog sniffed him out around the corner.

Police say Sequonie Suarez, 27, of Dorchester, started by setting an oil truck on fire outside 87 Norwell St. around 1 a.m. After firefighters doused the flaming oil truck, Suarez set a trash barrel on fire on Waterlow Street, about three blocks away from the remains of the oil truck, police say.

Then, around 2:30 a.m., police report, a resident across the street from where the oil truck went up in flames looked out a rear window and spotted a guy piling stuff up against a fence and lighting it on fire.

Officers responded with a tracking dog, who they say found Suarez at Radcliffe and Vassar streets, around the corner from Norwell. He will be arraigned Tuesday in Dorchester District Court on one count of arson of a motor vehicle, two counts of burning personal property and trespassing, police say.
