HOUSTON (AP) — Houston police are searching for a driver who they say fatally hit a 56-year-old bicyclist with a school bus and drove off.  

Bobby Brooks of Houston was pronounced dead at the scene on Wednesday. Police say Brooks was riding through a crosswalk when the yellow bus hit him while making a turn.

Police say they don't know who the bus belongs to or where it was going. A Houston school district spokeswoman says the vehicle wasn't a district bus or one contracted to transport its students.

It's unclear if anyone else was onboard.

Police are investigating.
