An 84-year-old woman has died of her injuries after she was struck by a cyclist last month in a hit and run, Toronto police announced Thursday.

The collision happened in the area of Parliament and Spruce streets on Sept. 24. Police say the woman was walking across the street with a 75-year-old man when a cyclist struck them. The cyclist then fled the scene before police arrived.

The woman was taken to hospital with a broken shoulder and pelvis. The man received minor injuries.

Police confirm the woman died of her injuries last week.

The cyclist is described as a white man, approximately 5'8" with a heavy build, possibly wearing a green bicycle helmet. Police say several people witnessed the collision, and some spoke to the man on the bicycle before he took off.

Investigators are now asking for help in identifying the cyclist. Anyone with information is asked to contact police or Crime Stoppers.
