The driver of a minivan forgot to set the van's parking brake Thursday morning, resulting in the minivan rolling backwards into an office building in the 1500 block of South Boston.
The driver told Tulsa Police the minivan's battery had died, so he parked it in an alley and got out.
That's when the minivan rolled into the front of a nearby office building, damaging the van and the office building.
An office worker sitting at her desk had just gotten up when the minivan hit. She was not injured.
No word if Tulsa Police issued a citation to the driver.
