Wiltshire Police are trying to trace the owners of a large greyhound dog after an incident in Calne in which a man was left with a fractured pelvis.
The victim, who is in his 60s, was walking his dog in the playing fields next to Anchor Road at around 11.30am on 18 March 2018 when a greyhound came running over at speed and knocked him to the ground.
He suffered a fractured pelvis which required surgery to fit screws and a metal plate.
The owners of the greyhound were in the park at the time and did fetch their dog but left the scene without exchanging details.
Officers have released a photograph of a woman they would like to speak to in connection with the investigation.
