Pennsylvania state authorities have arrested and charged a Harrisburg man they said set fire to the governor’s mansion while Gov. Josh Shapiro and his family slept, forcing them to evacuate early Sunday before the blaze severely damaged part of the building.

The man, identified as Cody Balmer, 38, jumped a fence and managed to evade state troopers after he broke into the building, the authorities said. He fled the scene and was arrested after turning himself in to the police on Sunday afternoon, officials said at a news conference.

Mr. Balmer was charged with attempted murder, arson and terrorism
