A BRIT dad accused of trying to drown his daughter-in-law – who is also claimed to be his girlfriend –  will be formally charged with attempted murder in the US.

Mark Gibbon, 62, was arrested at the luxury Solterra Resort in Florida last Sunday after allegedly forcing 33-year-old Jasmine Wyld’s head underwater “multiple times” in a furious row over his will.

The wealthy lighting engineer – who has worked with Mick Jagger, Ed Sheeran, Sam Smith and the late Queen – is expected to apply for bail but may be refused it, as US prosecutors reportedly see him as a “flight risk”.

Gibbon is claimed to have struck a relationship with Ms Wyld – who was once married to his son Alex.

The Brit dad, of Beaconsfield, Buckinghamshire, has already appeared in court on two battery charges, each carrying $1,000 bail.

But a source said his attempted murder hearing is “a different level of seriousness” as he is expected to be charged tomorrow.

The insider told Mail on Sunday: “He could technically be eligible for bail but because of his wealth and the fact he is a British citizen a judge may consider him too high a flight risk.

“If bail were to be considered then he would have to surrender his passport and have to agree to wear a monitoring device.”

Officials at Polk County Prison refused to comment on his detention conditions for safety reasons, but he is expected to appear before the judge in orange prison overalls.

“He will be taken from his cell and transported to court in shackles and handcuffs but they may be removed inside the courtroom at the discretion of the judge,” the insider added.

Wyld’s nine-year-old daughter is said to have leapt into the pool to try to “save” her mother.

Police reports claim Gibbon’s alleged attack left her with scratches and bruising.

Both Gibbon and Wyld told police they are not romantically involved, although detectives are reportedly probing claims they have been lovers for years.

Neighbours in Beaconsfield described Wyld as Gibbon’s “girlfriend” and said she was often seen at his £800,000 semi-detached home.

One neighbour told The Sun: “Everybody is shocked by this.”

Another, who said she was Wyld’s friend, recalled: “Jasmine used to stay here a lot with the children. But I don’t want to say much more because she is a friend of mine.”

Family insiders claim tensions erupted years ago when Gibbon’s son Alex allegedly found Wyld in his father’s bed.

“About four years ago there was a big fall-out,” one source the Daily Mail.

“Alex went up the stairs and found Jasmine in his father’s bed. They had a massive row. It’s torn the family apart… there’s been so much bad blood between Alex and his dad.”

Alex, 32, and Wyld separated in 2021 but share two young children.

The feud deepened when Alex was jailed for driving an £80,000 Porsche Cayenne into his father during a public row.

He was released six months ago, and father and son no longer speak.

Gibbon, who also runs hairdressing business Sage Hairdressing, allegedly pushed Wyld underwater during the Florida row after telling her she was not the main beneficiary of his will.

He reportedly admitted pushing her but denied trying to kill her, claiming they had both been drinking, she slapped him, and the situation escalated.

Polk County Sheriff Grady Judd said: “We expect vacationers to behave while they visit with us, just as we expect our life-long residents to do the same.

“Because Mr Gibbon couldn’t control his anger he may find himself spending a lot more time in Florida than he had anticipated.”

If convicted on all charges, Gibbon could face up to 20 years in jail.
