A former campus security officer at Lakewood High School was arrested and charged with sexually assaulting a student, police said Wednesday.

On Aug. 13, a former Lakewood High School student told police she was sexually assaulted by a school employee about 10 years ago, the police department said in a Wednesday statement.

The woman told investigators that in her junior and senior years of high school, Rubel “Tim” Martinez — a campus security officer with Jefferson County R1 School Security — repeatedly assaulted her on and off school grounds, police said.

Martinez worked as a campus security officer at Jefferson Junior and Senior High Schools and at Lakewood High School from 2006 to 2022, according to the police department. He also ran an after-school clown club at Lakewood High School.

Lakewood officers arrested Martinez on Friday and he was booked into Jefferson County Jail, where he is being held on a $20,000 cash-only bond, according to court records.

On Tuesday, the First Judicial District Attorney’s Office charged Martinez with one count of felony sexual assault on a child by a person in a position of trust, court records show.

Lakewood police officials said anyone with information related to the investigation should call detectives at 303-987-7229.

Martinez is next set to appear in court on Friday for a return filing of charges hearing.
