The Only Way is Essex star Jake Hall died from a chest injury caused by broken glass, investigators say.

The 35-year-old suffered head wounds after allegedly turning aggressive and trying to harm himself during a party at a £200-a-night Majorcan villa he was renting.

But sources close to the ongoing probe said today the worst injury he suffered was a chest wound caused by a shard of glass from the door he crashed into at the property in Santa Margalida in the north of the island early on Wednesday morning.

The autopsy was expected to take place today in the Majorcan capital Palma although the results will be sent to an investigating judge and will not be officially released as is normal in Spain.

The insider said: 'The thorax injury was the one emergency responders at the scene felt was the most traumatic one and most likely to have been fatal.'

Cops confirmed today the reality TV star and model's death is being treated as accidental.

A Civil Guard spokesman said: 'There is nothing pointing to it being the result of a crime at this stage.'

An investigating magistrate in the town of Inca is understood to have been sent an initial police report and will be receiving the autopsy results as they become available.

The results of the post-mortem will yield only partial answers and will be complemented with tests on tissue samples sent to a specialist lab on the Spanish mainland.

Those tests will help cement suspicions Jake was high on drink and drugs when he died.

The investigating magistrate will only order the Civil Guard, the response police force, to conduct more inquiries if he suspects any criminality has occurred and could have contributed to the star's death.

Civil Guard officers are understood to have quizzed several other people at the house where the death occurred, believed to be four men and two women. Their nationalities have not been released.

Officers based in Santa Margalida informed HQ around 7.30am on Wednesday morning about the discovery of a man's body at the rented property.

Respected local paper Ultima Hora reported later the same day a neighbour had heard a group of people talking about drugs the day before the horror incident.

The neighbour told the paper they 'hadn't been causing problems' and seemed 'relatively normal' although he admitted to being scared by how one of the group members looked.

He claimed he also heard them talking in English about buying a property in the area, and reported he had been woken up a few hours before police arrived, saying: 'It must have been around 2am. It was late but I was still awake.

'I began to hear a very loud noise, as if they were drilling something. I felt the walls vibrate. They stopped after about five minutes and then I fell asleep.'

Another neighbour said she hadn't heard anything out of the ordinary and when she walked her dog just after 7am on Wednesday didn't see anything strange.

The dead man's body was removed around 1pm on Wednesday afternoon.

A source close to the probe said in the aftermath of the horror incident: 'Witnesses have told investigators he had been out partying all night and decided to carry on the party back at the place he was renting.

'It appears from what police have been told that he became agitated, possibly from alcohol and other substances he may have consumed which is something an autopsy will determine, and at one point turned aggressive and tried to harm himself by banging his head against things.

'Police are still investigating but it seems like he could have thrown himself against a door with glass in it, breaking it and suffering fatal injuries from the shards that broke off.'

Another insider said before it emerged Jake Hall was the dead man: 'The hypothesis that he died while self-harming after a possible combination of too much alcohol and possibly drugs is still the one that appears to be the most likely at this stage.'
