A pensioner was left with a broken hip after he was hit by a cyclist outside a Corby supermarket.
The man, 71, was hit by a man on a bike sometime between 9.40am and 10.20am on Sunday outside the Morrisons store in Oakley Road, Corby.
After the collision, it is believed the cyclist then approached the pensioner and pushed him onto the car park floor.
The cyclist was tall and skinny and was wearing a cap.
A spokesman for Northamptonshire Police said: “Two members of the public who were in the car park at the time helped the victim after the attack, and we are appealing for them to come forward. One of these was driving a small red hatchback car.”
Witnesses, or anyone with any information about this incident, can call Northamptonshire Police on 101. Alternatively, information can be given anonymously to Crimestoppers on 0800 555111.
