Jury selection has started for a former police officer accused of beating a teenager.

Drew Ryser is on trial for his role in a videotaped beating of then 15-year-old Chad Holley.

The beating led to charges against four Houston police officers.

In April, Raad Hassan and Phillip Bryan pleaded no contest to official oppression. They were sentenced to two years of deferred adjudication and ordered to pay a fine.

Andrew Blomberg was acquitted of the charges.
