London police say no charges will be laid against the drivers involved in separate collisions involving a cyclist and a skateboarder this week.
On Wednesday afternoon, a northbound cyclist was struck by a transport truck on Highbury Avenue near Brydges Street.
While the driver and the truck left the scene, they were later located with the help of witnesses, according to officials.
Police had said that it was possible due to the size of the truck, that the driver was unaware that he had even been involved in a collision.
On Monday morning, a 20-year-old man was involved in a collision with a transport truck at Dundas and Adelaide streets.
Police say the skateboarder was westbound on Dundas when he collided with a southbound truck.
Both crashes shut down area roadways for several hours.
The victims in both incidents remain in hospital in critical condition.
