An advocacy group's attempt to mark the death of a Toronto woman who was killed in a cycling accident last month was short-lived after police chased them away Saturday.

The Urban Repair Squad, a group which fights for the rights of cyclists, painted blue bike lanes at Dundas Street West and Sterling Road Saturday morning to mark the death of Jenna Morrison. Morrison died after being struck and dragged under a truck's wheels on Nov. 7.

The group fled after five police cars arrived on the scene just before noon, leaving behind their bicycles and paints.

Morrison was killed as she rode her bike in the city's west end. She was turning on to Dundas Street West from Sterling Road when she collided with a truck and suffered fatal injuries. Morrison, who had a young son, was pregnant at the time.

This was the third attempt to recognize the death of the woman. Previous attempts included bike stencils on the road and a bike lane crafted out of bits of garbage.

Morrison's death has served as a rally cry for better bicycle safety. It also prompted Olivia Chow, the NDP's transportation critic, to introduce a private member's bill calling for the use of guards on all heavy trucks in the country.
