The unidentified sergeant collided with a school bus (no children aboard) in Houston.

An HPD spokesman said the bus driver ran a stop sign and caused the accident. But other witnesses said the officer was the one who ran a stop sign.
The bus driver said she thinks he'd been drinking.

"He smelled drunk and he had beer and wine opened in his car," Teresa Argueta said.

Other witnesses said officers at the scene threw a towel over the open containers and threatened to arrest anyone who took photos.
