An elderly London couple has died in hospital from their injuries after being hit by a car a week ago.

Police say 85-year-old Ron Frank and his 80-year-old wife Bonnie Frank were knocked to the ground by a car that was backing out of a driveway on Staffordshire Road.

The couple both died Tuesday.

Police have charged a 29-year-old motorist, but the name of the driver has not been released.
