A 24-year-old man is in custody after an 18-year-old woman was sexually assaulted while she waited for a GO bus in Ajax last month.

At around 9:30 p.m. on July 18, a woman was waiting for a bus at the Ajax GO Station on Westney Road South when a man approached her and started an unwanted, sexually explicit conversation with her.

The woman told police she was then touched inappropriately.

Police say she then walked toward the bus but stopped when she saw the man start a conversation with another woman.

The woman told police she interrupted the conversation with the female before continuing toward the bus.

According to police, the woman alerted the bus driver of what happened once she realized the man had followed her onto the bus.

At that point, the driver refused to let the man onboard the bus. The woman reported the incident to police the next day.

Jarushan Uthayakumar, 24, of Ajax was arrested and charged with two counts of sexual assault.

He was remanded in custody while he waits for a bail hearing.

Anyone with new information about this investigation is being asked to call Det. Const. Sabo of the Major Crime Sexual Assault Unit at 1-888-579-1520, ext. 5248 or Crime Stoppers at 1-800-222-TIPS (8477).
