A house fire on Watt Avenue -- south of Arden Way -- is under investigation. 

Metro Fire  Battalion Chief Anthony Kastros says it started in the garage of the home. 

"We arrived to find a well, well-involved garage that was extending into the house and attic. Crews made an aggressive interior attack," Kastros said. 

No one was found inside the home and no firefighters were injured. Kastros says the house appeared to be boarded up and abandoned.
