Not according to the quoted article from The Thaiger:
"Panya insisted that only one officer tortured him on the day. He remembered that the officer had a prosthetic leg. He covered Panya’s head with a black plastic bag, ordered Panya to take off his shirt, and lowered the air conditioning temperature. The torture and threats went on for over nine hours, and Panya confessed to the murder because he was exhausted and suffering."
