A construction magnate and more than a dozen other people have surrendered to police on criminal negligence charges for the collapse of a Bangkok high-rise during a March 28 earthquake.

A Thai construction tycoon and 14 others surrendered to police on Friday over a building collapse that killed nearly a hundred workers during a powerful earthquake in March, authorities said. The partially built 30-storey State Audit Office tower in Bangkok was the only building to collapse from tremors emanating from the powerful 7.

Ninety-two people were confirmed dead in the rubble of the building. The building was the only one in Thailand to collapse in the earthquake that was centered in neighboring Myanmar.
