Prince George’s County authorities said a man was arrested Friday morning in Oxon Hill on suspicion that he set a two-story house on fire and assaulted a police officer.

Firefighters were alerted to a blaze at 7:30 a.m. on the 5600 block of Woodland Drive. Police earlier had come to the address in response to a domestic situation, county fire spokesman Mark Brady said.

When firefighters arrived, they found flames on the first floor and a man walking on the roof. He jumped down to escape the heat, Brady said, and was taken into custody. They did not identify the man.

Firefighters extinguished the fire in about 15 minutes and reported no injuries.
