The victim has been taken to hospital and is said by a witness interviewed by CP24 to have lost a lot of blood. The attacker is in custody. The witness interview detailed passengers preparing to exit the train at College when the attacker produced a weapon, apparently an ice pick, and began to stab a man. The witness said the attacker and victim were not known to each other.
