Police are still investigating the death of a man who was found unconscious in a school playing field nine months ago.

The man in his 40s was discovered near the running track at Canterbury Academy at about 4.15am on May 26 last year, after suffering a serious head injury.

Paramedics rushed to the scene in Knight Avenue and the man was taken to a local hospital, but he sadly died three days later.

Detectives from the Kent and Essex Serious Crime Directorate launched an investigation.

Three men, who were all known to the man, were arrested in connection with the incident.

The day after the man was found, police forensics teams spent hours at a bungalow in New Dover Road as part of their probe into what had happened.

Officers also appealed for any witnesses to a disturbance that happened in Union Street, Canterbury, in the late afternoon of May 25, to come forward.

On July 20 a fourth man, a 33-year-old who was also known to the man who died, was also arrested.

All four men were placed on bail and have since been re-bailed on several occasions.

But their bail came to an end last week when all four were released under investigation.

Police say the man's death is being treated as "unexplained", and the investigation remains open.
