Two British tourists aged 29 and 27 have been found dead at a pool in Portugal. A friend of the two men found them in the resort of Albufeira after a night out partying.

News of the double tragedy first emerged late last night. The alarm was raised around 4.30am on Tuesday, but efforts by emergency responders to revive them proved unsuccessful. Today it emerged one of the friends of the men had found them “lifeless” at the bottom of the pool and called for help.The unnamed friend has already been quizzed by police, who are treating the deaths as accidental at this stage while they await the results of autopsies.

Some of the men’s friends told investigators the pair didn’t know how to swim and had been drinking before heading back to their holiday accommodation, according to local press.

The owner of one of the apartments on the unnamed complex, where the pool opening hours are 8am to 9pm, told Portuguese daily Correio da Manha: “They were with a group of friends. It was one of them who found them in the swimming pool.”

Albufeira has come under the spotlight in recent weeks following the deaths of two British tourists in quick succession amid a town hall decision to introduce high fines for holidaymakers who flout a strict new good behaviour code.

On June 4 tragic Scots tourist Greg Monks was found dead near Albufeira after going missing a week earlier in the resort.

The 38-year-old plant mechanic from Glasgow is believed to have lost his life after jumping over a wall and falling down a steep hillside during a night out with his stag do friends.

A search for him was launched on May 28 and his parents and girlfriend Nicole Kelso flew to the Algarve to help with the efforts to find him.

Around four hours before Greg’s body was found by police, another young British tourist was found dead behind a steep drop at the back of a residential block by Albufeira’s Old Town.

The 21-year-old, also said to have gone out drinking with pals and thought to have become disorientated as he tried to get back to his hotel, was never named.
