Five helicopters airlifted a team of border patrol policemen on Saturday morning to resume search of a shaft over the Tham Luang Cave.
Deputy Police Commissioner-General Pol General Veerachai Songmetta, who heads the team, said the team will climb down the 60-metre deep shaft from Pha Mee Mountain to try to reach three chambers on the side of the cave where the 13 young footballers may have been trapped since last Saturday.
On Friday, the police had reached the bottom of the shaft but had not entered a hole believed to be connected to the chambers, Veerachai said.
The border patrol policemen are now equipped with wireless communications tools that would feed their pictures back live to the top of the mountain where Veerachai is based for analysis.
