This was the moment the brother-in-law of murdered Brit millionaire Alan Hogg arrived at the crime scene today (September 26) pointing to the spot where he buried the couple.

Warut Satchakit, 63, and Kittipong Kamwan, 24, and Phia Kamsai, 63 arrived at the house in Phrae, northern Thailand, where they were taken to the two-metre deep grave where the bodies of Alan, 64, and wife Nott, 61, were found yesterday.

In the video, Warut, left in a black top and jeans, is seen in handcuffs pointing to the hole. He is then joined by the younger man Kittipong in pink shirt.

The group used Alan's own digger to make a deep hole before they were both thrown next to each other in on September 18 at 8pm.

The brother-in-law stopped and was grilled briefly by reporters but covered his mouth with his shirt and did not speak. He was then bundled into a police truck.

Cops said they had been interrogating him all night and that he had confessed to murdering his sister, Nott, by beating her with a hammer as Kittipong held her down in the garage of the sprawling home on September 18 at 6pm.

The third man Phia Kamsai, 63 - the hitman who receive 50,000 baht to shoot Alan with a shotgun - arrived separately and was pictured sitting outside Warut's house in a white t-shirt.

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.
