HOUSTON (AP) - A Houston police officer under indictment for a botched raid of drag racers in a Kmart parking lot last summer resigned from his job on Tuesday, before a scheduled administrative hearing in his case.

Sgt. Ken Wenzel, one of 13 officers suspended with pay over the Aug. 18 raid, decided to resign hours before his meeting with acting Police Chief Tim Oettmeier. Wenzel was a a 26-year veteran of the department.

The other officer also indicted in the case, Capt. Mark Aguirre, a 23-year veteran, went ahead and met with Oettmeier and will find out in a few days whether he will be fired.

"Our position is that we did nothing wrong, either criminally or administratively," said Terry Yates, a lawyer representing Aguirre in the departmental investigation.

Yates said he expected the police department to fire both men. Aguirre will fight any departmental discipline, he said.

In December, a Harris County grand jury indicted Aguirre and Wenzel each on five counts of official oppression.

Aguirre oversaw the raid designed to curb drag racing, and Wenzel was a sergeant in his patrol division.

When police found no evidence of drag racing, officers swept through the parking lots of the Kmart, and a nearby Sonic Drive-In and James Coney Island restaurant and made arrests.

Many of the more than 270 people arrested were customers and they were charged with trespassing and curfew violations.

The arrests sparked a public uproar, and prompted the police department to launch its largest-ever internal affairs investigation.

All charges against those arrested in the raid were eventually dismissed. They are being expunged from their records at city expense, but several lawsuits have been filed against the city and police department.

Aguirre and Wenzel are expected to go to trial either in the spring or summer.
