Sussex police are appealing for witnesses after the mystery death of a cyclist in Tower Hill, Horsham on Saturday.

The 53-year-old man from Horsham was found collapsed in the road around 10am on Saturday October 4.

Kent, Surrey and Sussex air ambulance attended and an off-duty doctor, paramedics and members of the public tried to resuscitate him, but despite their efforts he was pronounced dead at the scene.

The road was closed near its junction with Christ's Hospital Road while the incident was dealt with. A post mortem examination is to be carried out to try to establish the cause of the cyclist's death.

Police have asked that anyone who saw what happened and who has not yet spoken to them should email collision.appeal@sussex.pnn.police.uk or phone 101, quoting Operation Mendip.
