OKLAHOMA CITY - The Oklahoma City Fire Department is investigating after a window unit caught fire at a church Saturday morning.

Fire crews arrived at The Lords House Church at SW 37th and Portland shortly after 8:00 a.m. Saturday.

The housekeeper of the church went inside and turned on a light, and said she heard a pop. She then stepped outside to check on things and saw the window unit was on fire. The fire reached the peak of the church before being put out by the fire department.

There were no injuries.

Initial reports by the Oklahoma City Fire Department indicate the cause was electrical, but they are still investigating at this time.
