HOUSTON -

A former police officer accused of beating a teenage burglary suspect took the stand in his own defense on Friday.

Andrew Blomberg, 29, is the first of the four former Houston Police Department officers to stand trial in the alleged attack that was caught on video. He is charged with official oppression, a misdemeanor.

An attorney for Blomberg said his client was a "hero" who tried to secure a potentially dangerous suspect, and that he had not kicked Chad Holley, who was 15 at the time of the 2010 incident.

Blomberg told the jury that he and other officers believed that Holley was armed and may be a gang member.

He said he twice ordered Holley to put his hands behind his back, but Holley did not comply.

Blomberg told the jury that he did not kick Holley's head or neck, but he did use his feet to force Holley's hands behind him.

Holley was not armed when he was arrested.

Two retired Texas Rangers took the stand to say that Blomberg did not use excessive force.

Maurice Cook, a retired senior captain who spent 23 years with the Rangers, said that even though Holley was on the ground, he was still a potential threat.

Police Chief Charles McClelland told the jury Tuesday that he was "very disturbed" when he watched the videotape of the incident.

"I believe a crime had been committed," McClelland said. "I saw HPD officers conducting themselves in a manner that was against training, policy and state law."

After court, McClelland talked to the media. Defense attorney Dick DeGuerin asked the judge to hold McClelland in contempt for doing that. DeGuerin said McClelland should not be talking to anyone about his testimony because he is a witness. The judge denied that motion.

On Wednesday, the defense showed a new aerial video of the arrest.

Officer Lewis Childress, a 25-year veteran of the department, testified that he thought Holley was already handcuffed when he arrived. He told the jury that he had used in feet before when making arrests.

When Holley arrived at the hospital after the incident, he had a bruise on his forehead and one of his eyes was red. Prosecutors said those injuries were consistent with a beating, but the defense called a doctor to testify that the red eye was caused by something else.

Dr. Larry Cohen, an optometrist, said Tuesday that the redness was caused by a sexually-transmitted disease, not trauma.

Cohen has not examined Holley and made that determination by going through Holley's medical records. Cohen is being paid $500 an hour by the defense.

One of the other eight officers accused in the beating took the stand for the prosecution on Monday. He was not fired and now works undercover in the gang unit.

The officer said he jumped on Holley's back and grabbed his arm while he straddled his legs and waist.

"I was afraid he had a gun and that one of us would get hurt," the officer said.

On May 4, a 37-year veteran of the training academy testified that when he watched the videotape of the arrest, he saw Blomberg stomp on Holley's head. He said no HPD officer is trained to do that, and the technique used did not make sense.

"He's treating the suspect poorly," the training officer said.

Holley, 18, was the first witness for the prosecution.

Holley testified that he and three friends stole a piano keyboard and some vodka from a townhome in southwest Houston in March 2010. Later that day, police stopped the youths' truck and Holley ran. He said a police car knocked him over and as he lay on the ground he put his hands on his head to indicate surrender.

That was when "the kicks started coming," said Holley, who is black.

"I started feeling people on my back. I felt one hard blow," he said. "It felt like knees and I don't know kicks ... I lay there," not fighting back. Holley said he briefly lost consciousness and the next thing he remembers is waking up in the back of a patrol vehicle.

Holley testified for most of the day. The videotaped beating was shown to jurors at the end of Holley's testimony.

Prosecutor Clint Greenwood told jurors that the officers were out of control.

"The defendant and his fellow officers methodically delivered their own brand of justice not in this courtroom but in the side of a street in southwest Houston," Greenwood said.

Holley's arrest and alleged beating was captured by a security camera at a nearby storage business. In the video, Holley can be seen on the ground, surrounded by at least five officers. Officers appear to kick and hit his head, abdomen and legs.
