A diver and industrial engineer have conducted new tests in a Spanish resort pool where a British pastor and his two children drowned.

Pastor Gabriel Diya, 52, his daughter Comfort Diya, nine, and his son Praise-Emmanuel Diya, 16, died on Christmas Eve at the Club La Costa World holiday resort in Fuengirola, Spain.

Hotel operator CLC World Resorts and Hotels said "diligent and exhaustive" police investigations had confirmed the pool was working "normally" and there was "no malfunction of any kind".

However, the pastor’s wife, Olubunmi Diya, has maintained that faulty pool equipment caused the deaths.

Mrs Diya's lawyer got permission from a Spanish court to hire professionals for further pool testing.

According to The Sun On Sunday, a diver and industrial engineer have checked the pumps and water flow in the pool.

According to a statement issued by the Guardia Civil in Spain days after the drownings, its investigation points to the incident being an accident caused by the victims' lack of swimming expertise when in the deep zone of the pool.

Mrs Diya said the three of them knew how to swim.

She said in a statement shortly after the tragedy: "The whole family, all five of us went to the pool together and were all present when the incident occurred.

"The children were not left unattended.

"We followed the instructions displayed by the poolside at all times.

"The children went into the pool using the steps but found themselves dragged into the middle, which was deeper and called for help when they could not get out.

"My daughter did not fall into the water.

"My husband went in via the steps trying to help the two struggling while I ran to the nearby apartments shouting for help to assist my husband.

"By the time assistance came, the three of them were under the water."

Mr Diya was a pastor of a London branch of Redeemed Christian Church of God (RCCG).

Neighbours of the family in Charlton said they were left "devastated" and "sad" by the deaths.
