A FOUR-year-old British boy has drowned in a hotel swimming pool in Tenerife after suffering a possible cardiac arrest.

The youngster died at the Paradise Park hotel in Los Cristianos despite desperate attempts to save his life from paramedics and an air ambulance crew.

The alarm was raised at 3.40pm this afternoon.

Efforts to revive the youngster by members of an emergency response team proved unsuccessful and he was pronounced dead at the scene.

A receptionist at the four-star hotel - full name Hotel Paradise Park Fun Lifestyle - declined to comment this afternoon.

National Police have launched a probe into the tragedy which is being coordinated by a local investigating judge.

A spokesman for a local government-run emergency response coordination centre confirmed a four-year-old boy had died at a hotel in Los Cristianos.

The centre said in a statement: “An alert was received at 3.40pm informing us that a child who appeared to have been involved in a drowning incident and was suffering possible cardiac arrest, had been pulled out of a swimming pool at a hotel in the resort.

“Efforts to revive the youngster using CPR proved unsuccessful and he was confirmed dead at the scene.

“Local police cooperated with the emergency services and habilitated an area for an air ambulance to land near the hotel complex.

“National Police took charge of the body until court workers arrived.”

Well-placed sources confirmed the youngster was British.

It was not immediately clear what caused the tragedy.

A Foreign Office spokesperson said: "Our consular staff are supporting the family of a British child who died in Tenerife and are in contact with Spanish authorities.”

The hotel where the latest tragedy occurred has five swimming pools and four hot tubs.

Travel websites say the 376-room hotel offers wonderful views over the Bay of Los Cristianos and Mount Teide from a rooftop terrace.

It is popular with British tour operators and holidaymakers.
