TORONTO -- Toronto police are seeking a suspect in a string of suspected hate crimes at various subway stations.

Investigators say the incidents took place last Friday and Sunday.

They say a man allegedly spat on someone at Christie station last Friday morning.

Then, on Sunday morning, it's alleged the same man spat on a woman at Lansdowne station and yelled racial slurs at her, and threatened a bystander who tried to intervene.

About an hour later, police say the man spat on a woman at Wellesley station.

In all three cases, the suspect took off before investigators arrived, but security images have been released.
