On Tuesday, police said the driver involved may have acted intentionally, though investigators provided few additional details. Police have not announced any arrests in connection with the incident at this time. The collision happened on Nelson Mandela Walk, a pedestrian walkway just south of Gerrard Street that sits between the campus library and an academic building. It happened just before 2 p.m. The driver was in a dark green sedan with a smashed-in windshield, police said, with the license plate DEDZ 565 Two people were taken to hospital, though all four who were hit are expected to survive. None were TMU students or staff, though the incident left many on campus shaken. Third-year TMU student Isaac Meng told reporters he was studying in the library next to the walkway around 1:50 p.m., when he heard a loud, revving sound. He said one of his friends started calling out loudly to him, "A car just crashed [into] people! A car just crashed [into] people!" Meng said he rushed to the window, but the car was already gone. He says he saw a man lying on the grass, apparently unconscious, as people tried to call to him. At that point, he and his friend called the police, he said. "It was crazy," Meng said, saying it was like a scene out of a movie. TMU taking steps to block vehicles from walkway TMU said Wednesday it's working with the City of Toronto on adding safety measures to Nelson Mandela Walk, while keeping the walkway open to emergency vehicles. "As an immediate measure to ensure pedestrian and public safety, planters have been placed at the main entrances to Nelson Mandela Walk," it said in a statement. Mayor Olivia Chow and several TMU officials discussed the incident while attending a gala event put on by the university late Tuesday. TMU issued a safety alert online at the time. "Our thoughts are with those who have been injured and impacted by this incident," TMU said in a statement.
