OKLAHOMA CITY- Fire crews are still looking into what caused a vacant house to catch fire Sunday morning.
Firefighters rushed to a duplex in the 2100 block of W. Park Pl. early Sunday morning and spotted flames shooting from the attic.
Crews say they were able to get the fire under control in less than a half hour.
Authorities say it appears that the duplex was vacant since the doors and windows were boarded up and the utilities were shut off.
The fire is being investigated as suspicious.
