Holidaymakers have been injured and more than 150 people evacuated after part of the dining room of a hotel in Majorca collapsed. Several customers have suffered minor injuries and have been treated by the emergency services.

The emergency happened tonight in the popular tourist resort of Santa Ponça. The incident unfolded at around 9.30pm at the Rey Don Jaime hotel, located at number 4 Gran Vía Puig Major street. Several customers were eating in one of the dining rooms of the complex when for reasons that are being investigated, the ground gave way.

Photos published in Spanish newspaper Ultimahora.es show the dining room with floor slabs collapsed, with tables and chairs sliding sidewards and debris over the floor.

Firefighters from the Calvià station, together with ambulances, patrols from the Local Police and the Civil Guard, have rushed to the scene to help possible victims.

Ambulance crews have treated several people with minor injuries, with around 150 people evacuated as a precaution.

A full investigation will now be launched to determine why part of the floor has collapsed.

The incident is the second to happen in a Spanish hotel in the space of a few days.

The first happened in Benidorm where the roof of a restaurant in an hotel collapsed on Easter Sunday.

The noise of the ceiling crashing down in the restaurant of the Poseidon Palace hotel was so loud that even people in the swimming pool heard it.

Holidaymakers have revealed their horror at the incident which injured at least seven people, one of them a young boy.

But they said it could have been a lot worse as just the day before, the restaurant had been packed with 400 people who only left on Saturday.

One said: “It was a very tense moment. We arrived at that time to eat and people fled in terror without knowing what was happening.”

The incident, which is still being investigated, happened just after 2pm on Easter Sunday. The restaurant ceiling collapsed, bringing down a massive amount of debris, plaster-board, broken glass and even parts of the air conditioning.

Seven people were injured, five of whom needed treatment at local hospitals. They were aged between 30 and 80. A boy of eight and another tourist aged 78 were treated at the scene.

The nationalities of those injured has not been revealed but all those in hospital have now been discharged.

The company hotel says an in-depth inspection of the installation is being carried out, pending a technical report from the municipal architect.

The dining room at the Poseidon Palace has been closed and guests are using the restaurant of an adjoining hotel.

Tourists said it had been a great scare and were grateful that the restaurant was not packed.

One of those affected fainted, either due to tension or due to some previous pathology but the man immediately regained consciousness, according to the company.

“There has been no blood, everything was bruising,” said general director of Poseidon Hotels, Pere Joan Devesa who confirmed the cause had not yet been identified. If in an AVE train with all the technology they have they take time to specify the causes, here in 24 hours we cannot do it,” he said.

The hotel dates back to the 90s so deterioration has not been ruled out. A thorough inspection of the complete plasterboard installation is being carried out. A couple from Murcia said they were in the pool when the incident occurred. “There was a lot of noise and very scared people. It was all very striking because firefighters, police and ambulances arrived,” they told Spanish newspaper Informaction.es
