Cyclists are increasingly smashing into blind Londoners and their guide dogs after mounting the pavement and jumping red lights.
A survey by the RNIB found one in four blind and partially-sighted people were involved in a crash and seven in ten had experienced near misses.
Deborah Persaud was hurled to the ground by a cyclist who was riding on the pavement.
Ms Persaud, a civil servant who is partially sighted, suffered a damaged shoulder and hip in the collision as she walked home from Highbury tube station.
The force of the collision left her sprawled on the pavement.
She said her Labrador guide dog, four-year-old Lewis, laid down next to her to protect his owner.
To add to her trauma, Ms Persaud said the male cyclist then tried to ride off and only stopped when she called the police.
