At 8:00 a.m. on May 16, Mr. Premchai Karnasuta, authorized director of Italian-Thai Development Public Company Limited, surrendered to Bang Sue Police Station.
He arrived in a private van and was seen using a wheelchair, which was brought by a close associate. As Mr. Premchai was wheeled into the police station, reporters attempted to ask whether he admitted guilt, felt any concern, or wished to apologize to the public. However, he remained silent and did not respond to any questions.
Mr. Phimon Charoenying, who signed the structural engineering plans, Mr. Kriengsak Korwattana, Senior Executive Vice President of Italian-Thai, and other suspects also turned themselves in, accompanied by their personal lawyers.
Inside the police station, officers placed metal barricades to control the area and prevent the media from entering the interrogation zone.
