A retired British ''millionaire'' and his Thai wife have been missing since last Wednesday after a bitter family feud with his in-laws, police said today (September 24).

Businessman Alan Hogg, 64, and wife Nott, 61, were reported missing on Thursday (September 19) when a friend arrived at their home in Phrae, northern Thailand, having tried to contact them on messaging app Line.

Blood was found on the walls of Alan's swimming pool changing rooms - allegedly with signs someone had tried to wipe it away - and the couple's brand new white Ford Ranger pick-up truck had also been stolen.

The wife's brother, Warut Satchakit, was arrested over the disappearance after CCTV showed him entering the home and stealing their car on Thursday (19/09).

He was then released on bail with a 100,000 baht (2,350GBP) bond paid by his relatives after he denied any involvement but admitted stealing the motor.

Officers continued their hunt today checking the couple's home, swimming pool, reviewing CCTV footage from the area and ordering police divers to scour nearby rivers.

The couple's daughter, who lives in England, also flew in to help the search.

Major General Sanpat Praputsra said: ''The progress of the case is moving well and we're in control. Officers are working on the investigation day and night. The issue is likely to be a long-standing conflict within the family. We cannot find any other situations that are likely to have caused this.''
