This footage shows the three killers of British millionaire Alan Hogg, 64, and wife Nott, 61, being paraded around the house where they plotted the murder.

Phia Kamsai, 63, (white shirt) arrived with Alan's brother in law Warut Satchakit, 63, (blue shirt) and Kittipong Kamwan, 24, at the rundown wooden home in Phrae, northern Thailand, at 1:15pm local time.

Wearing riot police helmets, they were paraded to the public and pictured together for the first time. They were then taken to the hole where Alan and his wife were buried and discovered yesterday.

It was at the house - next door to Alan's mansion - that the group planned the murder of the retired businessman from Edinburgh, Scotland.

Smiling assassin Phia Kamsai - the man who killed Alan with a shotgun - is seen laughing in the footage (1:27) while sitting on the steps of the home.

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.

Lieutenant General Poonsap added: ''Today the two suspects returned to the scene to show how they buried Alan and Nott. All three men pointed to the scene.

''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.''
