Metropolitan Police chief Pol Lt-General Winai Thongsong told a press conference that, after receiving information a drug gang would transport a large amount of narcotics to the South through the terminal, police spotted the suspicious bags at 7pm Tuesday. They staked out the area until 10.30pm but no one turned up to collect the bags, so they seized them and found the drugs inside.
Forensic police had collected fingerprints and DNA evidence from the bags, Winai said, and the initial investigation identified a man and woman as suspects who placed the bags in the terminal. He said that after gathering more evidence, police were confident they would be able to issue arrest warrants soon.
