Arson investigators are trying to figure out how a duplex on Houston's southside caught fire.

The fire started around 2 a.m. Friday at the duplex on Mallow and Noel.

Firefighters made a fast attack on the fire that consumed the one-story, wood framed abandoned duplex.

Firefighters were able to quickly get it under control, but there was still a lot of damage.

No one was injured.
