A busy road in Newmarket has been closed after a man was found with unexplained and serious injuries.

Police have closed part of Moulton Road for "most of the morning", after a man was found with unexplained facial injuries.

The force was first called at around 3.20am after a man knocked on a resident of Moulton Road's door. They arrived to find the man had unexplained facial injuries.

Officers from Suffolk Constabulary have now closed "a short section" of the road in order to set up a crime scene.

A spokesman for the force said the injuries were serious and could have been caused by an assault, or a fall from a height. The investigation is currently centred around what caused the injuries and the circumstances in which the man sustained them.

The injured man has been taken to Addenbrookes by ambulance.

The spokesman added that the incident was not currently thought to be linked to the case of a man who was found with unexplained head injuries on Park Lane in the town in late August.

Officers have asked motorists to avoid the area and find another way around.

They said that the closure would not affect plans for a charity horse event later today. Police added they were working with The Jockey Club to minimise disruption.
