Pictured: Sir Richard Sutton’s stepson, 34, who has been arrested on suspicion of his murder

The stepson of millionaire hotelier Sir Richard Sutton has been arrested on suspicion of his murder.

Thomas Schreiber, 34, was detained by armed police on Wednesday night in Chiswick, West London, after Sir Richard, 83, was killed at his north Dorset home.

Sir Richard’s wife and Schreiber’s mother Anne, 65, had been wounded during the same incident and remains in a critical condition in hospital after suffering multiple stab wounds.

A Range Rover car that Schreiber was alleged to have been driving was tracked across six counties and brought to a halt in West London by armed police where he was dragged from the vehicle.
