A house fire in the Logan Heights area sparked an arson investigation Wednesday evening, officials said.
At around 4:30 p.m., police and fire crews were called to the 3000-block of National Avenue to investigate reports of arson. When officials arrived on scene, they found a home on fire, and a man barricaded inside a room.
The area was blocked off as firefighters tackled the blaze.
A short time later, the man in the room was taken into custody on suspicion of arson, officials said.
According to police, the man had been threatening to hurt his mother. When police were called, the suspect barricaded himself inside a room and began lighting things on fire.
Officials said the man may have also physically harmed himself, though that's still under investigation. He was taken to a local hospital with unspecified injuries.
The man's name was not immediately released. The San Diego Police Department said further details are forthcoming. The suspect will be charged with arson, and possible other counts.
The investigation is ongoing.
