The woman whose husband and two children drowned in the Costa Del Sol over the Christmas period may seek further investigations into their deaths.

Olubunmi Diya lost her nine-year-old daughter Comfort Diya, teenage son Praise-Emmanuel Diya, 16, and husband Gabriel Diya, 52, in the incident on Christmas Eve at the Club La Costa World in Fuengirola.

Mr Diya's Facebook account lists him as a pastor at Open Heavens London, a Christian religious group with origins in Nigeria, based in Charlton.

Mrs Diya, who survives her husband and two children, previously said all three could swim and claimed that "something was wrong" with the Spanish hotel's pool.

Her lawyer, Javier Toro, said engineers not related to the Spanish Police's own inquiries could be brought in for a "parallel investigation" into the tragedy after police said their own findings point to the incident being a "tragic accident".

The operators of the hotel where the deaths took place — CLC World Resorts and Hotels — said Mrs Diya's claims are "directly at odds with the findings of the police report".

In a statement the operator pointed out that police findings made it "clear that their exhaustive investigations have confirmed the pool was working normally and there was no malfunction of any kind".

An English translation of a Guardia Civil statement, released by the hotel operator, stated that tests had found "no irregularity" in the pool's system.

It said investigations indicated the accident was "caused by the lack of expertise of the victims when swimming".

Nevertheless, Mr Toro questioned that suggestion.

Mrs Diya's lawyer was quoted by the BBC as saying: "It's very rare for three people to die in the centre of a swimming pool - especially in the case of a tall, hefty man.

"Something must have happened apart from a simple error or simple accident."

The family, he said, were "not satisfied with the interpretation of it being a simple accident".

Mrs Diya for her part remarked that the family had followed the instructions displayed by the poolside at all times.

Mr Diya's Charlton-based faith group is part of the Redeemed Christian Church of God and worships at the St Richard's Church Centre in South East London.
