Firefighters called for help after awaking to a man screaming obscenities, banging on windows and attacking a tree, reports The San Diego Union-Tribune.
Police arrived and arrested the man on suspicion of felony vandalism. Video from the scene showed police taking a shirtless man into custody. He had blood on his head and face.
Firefighters later emerged and discovered nearby a fire at a house where the man lives. It was unclear if the fire was intentionally set.
