He covered his mouth with his shirt and did not speak before he was then bundled into a police truck.
Last night, Satchakit, 63, confessed to beating his sister Mrs. Hogg with a hammer in the garage while Kittipong Kamwan, 24, held her down, detectives said.
The third man, Phia Kamsai, 63, then allegedly blasted Mr. Hogg with a shotgun in the garden after Satchakit paid him £1,175.
Police Lieutenant General Poonsap Prasertsak said all three men had now been charged with premeditated murder. They will be held in custody while prosecutors prepare the case.
‘The interrogation has progressed and all three men have now confessed. The motive for this incident was personal problems between Mr. Warut and his sister and her husband.
‘Police are gathering more evidence and will extend the investigation to anyone who had contact with the men. The investigation will continue until it is resolved.’
Satchakit was arrested along with two friends yesterday morning. Images show the 63-year-old wearing a mauve shirt in custody.
The bodies were found by sniffer dogs two meters deep behind a duck pond outside their home.
They were excavated at 12 pm local time and have been sent to a hospital for postmortem examinations.
Mr. Hogg, from Edinburgh, was the director of a laundry company in the UK and had moved to Thailand several years ago.
His daughter Robyn Hogg, a 31-year-old production assistant, flew to Thailand from the UK when she found out her parents were missing. She is yet to comment on the tragedy.
Police arrested the hitmen on Tuesday after they linked them to Mr. Hogg’s stolen pick-up truck which was found and forensically examined yesterday.
The hitmen confessed to the murder and burying the corpses, police said.
Officers arrived at the home on Tuesday at 10.30am and used an excavator to dig an area next to the duck pond in the 32-acre grounds of Mr. Hogg’s gated three-story home, which boasts a swimming pool, summerhouse, a cattle farm, and geese.
The corpses were later found in a two-meter deep grave with their shoes still on.
Satchakit was initially arrested for stealing the couple’s brand new white Ford Ranger pick-up truck and was arrested again after the assassins named him.
Investigators found that the truck had been sold to nearby hill tribe people for £4,600 who then sold it to a man from Laos for £9,800 in Sukhothai last Friday.
The man, from Laos, then drove it to Ayutthaya on a business trip, until he saw reports that police were looking for the vehicle and he contacted authorities.

The man turned the truck over to police in Ayutthaya on Sunday. He and the two sellers were then taken to Phra That Chor Hae police station to be interrogated.
Officers began searching the grounds yesterday with sniffer dogs. They found a gardening hoe and a freshly dug hole – but they did not find the bodies until Tuesday.
The couple was initially reported missing last Thursday when friends had unsuccessfully tried to contact them on messaging app Line.
Blood stains, with signs someone had tried to wipe them away, were found in the swimming pool changing rooms. A phone had been left charging in the living.
Today suspects were marched back to the crime scene to show how it happened
Three Thai men who allegedly murdered a British millionaire and his wife were taken to the crime scene today to show police how they carried out the slaughter.
The bodies of Alan Hogg, 64, and his Thai wife Nott, 61, were yesterday found in the garden of their mansion in Phrae, northern Thailand after a six-day search.
Police initially said Mrs. Hogg’s brother, Warut Satchakit, paid three assassins to take them out after family feuds over money – but today detectives said he admitted carrying out the murders himself with two paid accomplices.
Satchakit was ‘angry and resentful’ at being ‘scolded’ by businessman Mr. Hogg for constantly borrowing money from the couple, police said.
He contacted a friend in a neighboring province who arranged a contract killer to shoot Mr. Hogg while he and another man beat Mrs. Hogg with a hammer at 6 pm last Tuesday.
This morning, all three alleged killers were taken to the house to show police what happened. Wearing police helmets in case anyone tried to attack them, they pointed to the two-meter hole where they buried the bodies after their gruesome crime. Three men who murdered Alan Hogg return to the crime.
The hitman who shot Mr. Hogg, Kamsai, 63, arrived separately from the other two.
Like the others, he was taken to Satchakit’s house, which is next door to Mr. Hogg’s house, to show police where the murders were plotted.
He was pictured smiling and laughing while sitting outside in a white T-shirt.
The group used Mr. Hoggs’s own digger to make a deep hole before they dumped the bodies at 8 pm, police said.
Satchakit, in a black top and jeans, was seen in handcuffs pointing to the grave. He was then joined by the younger assassin, Kittipong Kamwan, in a pink shirt who did the same thing.This was the moment the brother-in-law of murdered Brit millionaire Alan Hogg arrived at the crime scene today
