An appeal has been launched after a BMW’s rear windscreen was smashed while parked in Royston overnight – with a cyclist believed to have been injured in the crash.

Police are appealing for witnesses after an incident in Poplar Drive which saw a parked BMW 320d’s rear windscreen smashed.

The damage took place at some point between 11pm on Wednesday and 8am yesterday – when the owner returned to the car after parking it in the road the night before.

Officers believe – due to the nature of the damage – that a person riding a bicycle has crashed into the back of the parked BMW and caused the damage.

Det Sgt Sarah Gilbertson, from the North Herts Local Crime Unit, said: “We believe the person riding the bicycle would have been injured following the collision so we would like to make contact with them to ensure they are safe. I would ask anyone who has any information which could help us trace this person to please come forward and speak to us.”

Anyone with information should call Herts police on non-emergency number 101, quoting crime reference number G4/16/1099.
