(BangkokPost.com) About 30 People’s Alliance for Democracy (PAD) guards wearing masks on Wednesday took control of Suvarnabhumi airport’s air traffic control tower to check the daily flight schedule.
PAD security head Samdin Lertbutr together with a group of guards entered the air traffic control tower and negotiated with the airport officials. The group said they wanted to make sure that no flights will leave or enter Suvarnabhumi while checking whether Prime Minister Somchai Wongsawat’s flight would arrive at the airport.
Initially, airport officials permitted five of the guards to enter the tower, but the guards later requested the officials to let all of them go through to prevent the police from using the tower as a command centre against them.
They have also been quoted elsewhere as saying they will stay in occupation at the airport and keep it closed until the government resigns.
