A search and rescue team of border patrol police and park officials was this morning flown by a helicopter to Doi Pha Mee mountain to conduct more survey of a shaft found on Friday.
Pol Gen Veerachai Songmetta, the deputy national police chief, said the team which was equipped with a camera and other equipment would join another team which had advanced to the shaft site by foot.
According to Veerachai, initial findings from the team earlier dropped into the shaft at Doi Pha Mee showed there were three connected cave chambers with the first chamber about 40 metres deep from the shaft entrance, the second chamber about 50 metres and the third about 60 metres deep.
He said he believed the three connected caves were at the same level with the cave or tavern that the 13 victims were believed to have taken refuge.
The camera which was equipped with a transmitter would be placed inside one of the three chambers and transmitted images of the chambers to the receiver at the command centre.
Veerachai said the team which went into the cave would spend at most two hours there and had to come out in order to be replaced by another team.
