Subway riders are being warned of a man dubbed the ‘Subway Spitter,’ who is believed to have spat on three people of Asian descent in what police say are hate motivated crimes.

Officers say the man has narrowly escaped capture twice in the west end. Undercover cops have taken to riding the subway cars to find the suspect, who may be getting more brazen.

Police said they were alerted on three separate incidents in which riders were spat on within three days.

Officers said they responded to a report that a man had assaulted someone by spitting on them on the eastbound platform of the Christie subway station on April 9 around 8:47 a.m.

The culprit fled the area before he could be arrested by police.

Detectives were called again on April 11 around 11:12 a.m. to a similar spitting call, this time at Lansdowne station.

Police Const. Caroline de Kloet said the Lansdowne victim has come forward to file a complaint.

She (the victim) said “a man spat on her and then yelled anti-Asian slurs at her before threatening a bystander who tried to intervene.”

Police said the suspect fled the scene on an eastbound subway train.

Later that same day, police were called again to another report ‘that a man had assaulted a woman at Wellesley station by spitting on her and then fleeing the area.”

“Investigators believe the same man is responsible for all three assaults,” stated a police news release.

The suspect is described as 20-30 years old, 5’7″, with a slim build. He was wearing a black hooded jacket with horizontal white stripes, black toque, black shoes and was carrying a black backpack.

Though the other two victims have not come forward, police said based on witness statements, they too were of Asian descent, and so the assaults are being treated as a hate crime.

Anyone with information is asked to contact police at 416-808-1100 or Crime Stoppers anonymously at 416-222-8477.
