Two children are being comforted after they discovered a man's body on Southend seafront.

The children were out for a walk when they made the gruesome discovery by the Sealife Adventure on Eastern Esplanade at about 7.30am yesterday.

The murder squad were immediately alerted and the area was sealed and the area was sealed off as they began an inquiry into the man's death.

It was initially treated as suspicious, but last night, after a post-mortem examination, a police spokesman said: "Although the initial post-mortem exam has proved inconclusive, det-ectives are satisfied there was no foul play involved.

"However, further tests will be required in order to ascertain an exact cause of death."

Police believe the man lived in London and a formal identification was expected to be carried out today.

A report will now be compiled by police and the file submitted to the coroner so that an inquest can be held.

Earlier, a police spokesman had said: "He was found by two children. I think they are quite distressed.

"They will be interviewed at some point, but we will need to find out what the circumstances were before we put them through unnecessary interviews."

After the discovery, officers sealed off the area around the Sealife Adventure and the adjoining car park for forensic examination.

Neil Palfreman, 34, saw police arrive at the scene as he drove to work from his home in Eastern Esplanade.

He said: "As I came out of my flat, I heard a police car come past. I had a look as I was driving past.

"It was a man lying on his back, fully clothed, with his head facing towards the sea and his feet towards the road.

"He was just in that little side bit as you walk to the entrance of the Sealife Centre."

The Sealife Adventure was closed yesterday following the discovery.

Manager Lucy Hodge said of the gruesome find: "It was a shock for everyone.

"We are all very shocked and saddened."

Police are appealing for witnesses.
