This is the bizarre moment a six-year-old boy was seen working on a building site in Thailand - operating a digger. <br /><br />Tony Kolrian, 43, looked out of his office window in Bangkok on October 9 morning when he saw the youngster.<br /><br />The boy was on a construction site sitting in the seat of a digger as he lifted rocks from one pile to another, according to witnesses.<br /><br />Kolrian said he had asked staff working next to the construction site next to the city's Lumphini Park how old the boy was. <br /><br />He said: ''The boy was six-years-old. He was really good at using the backhoe. <br /><br />''I could not believe what I saw. Thankfully he was not employed to work there. He was just playing on the digger. His father was teaching him how to use it. He was doing it very well.''
