Crews battle early morning south Tulsa house fire

Crews were busy with a south Tulsa house fire early Saturday morning.

The call went out just after midnight for a residence near 57th and Memorial. It's believed the house is being remodeled, so nobody was at home when the fire started.

Heavy smoke could be seen coming from the attic and kitchen. There is said to be extensive damage to the home.

So far, a cause is still under investigation.
