A Calgary volunteer high school coach has been arrested and charged in connection with the alleged sexual assault and exploitation of a student at a school in the city’s southwest.
Police say 50‑year‑old Drew Alan Robertson met the victim when she was 15, using his coaching role at Henry Wise Wood High School to groom her before the assaults began. I
Investigators believe the alleged offences continued for nearly two years through school programs and extracurricular activities, and that Robertson also operated a gym near the school where many students trained.
The investigation began last week after an explicit video allegedly involving Robertson circulated in a parent–student group chat at the high school. Sgt. Chris Tudor of the CPS Child Abuse Unit said the video “was inappropriate and sexual in nature” and prompted the complaint that led police to begin looking into the allegations.
Robertson was arrested on May 13 and now faces charges of sexual assault, sexual exploitation, and making sexually explicit material available to children. He is expected to appear in court on Wednesday.
The Calgary Board of Education (CBE) confirms it reported the video to police and notified students at the school.
The board says Robertson will no longer be associated with any CBE school teams and that the school is offering support to students connected to the individual. Families are also encouraged to seek additional community supports as needed for their child’s mental health and well-being.
“We take this matter seriously,” the CBE said in a statement. “The school will continue to fully cooperate with the police investigation. As this investigation continues and to protect the confidentiality of those directly impacted, we are limited in the information we are able to share.”
Police say the victim is receiving support from the Luna Child and Youth Advocacy Centre. Karen Orser, the centre’s CEO, said they work to ensure families understand the process and know who to contact as the case moves forward.
“Coaches are supposed to be instructors, leaders and mentors,” Tudor said. “Sexual exploitation by a person in a position of authority is a betrayal of those values, and offenders must be held accountable.” He added that investigators currently know of no other victims.
Anyone who believes they are a victim of sexual assault is encouraged to report it regardless of when it occurred, and anyone with information about these or similar incidents is asked to contact police at 403-266-1234 or leave a tip anonymously through Crime Stoppers at 1-800-222-8477.
