A Thai woman was arrested at Suvarnabhumi international airport on Wednesday as she tried to smuggle about 2.3kg of cocaine, worth about 6.9 million baht on the street, into the country.

The woman arrived on a flight from Doha, Qatar, on a Qatar Airways flight.

Customs officials at the airport became suspicious and asked to have her luggage scanned and her backpack searched. They found the narcotic hidden in five bags of clothes in the backpack.

She was charged with trafficking in illicit drugs.
