The formber banker had suffered from lung cancer for years. Since 2010, he had appeared in courts, to fight a series of embezzlement charges, in fragile physical condition.
His funeral service will take place at Wat That Thong for 7 days.
Right to his final day, Krirk-kiat had to fight a number of embezzlement charges, brought against him after the collapse of BBC. He had been sentenced to a total of over 100 years of imprisonment for several counts.
BBC was brought to its knees on huge leverage and improper lending, under the guidance of his advisor Rakesh Saxena. Saxena is now facing his cases in Thailand, after living in exile in Canada for a decade.
Krirk-kiat and Pin Chakkapak, former president of Finance One, were deemed as key people behind the money game which led to the 1997 financial crisis. Unlike Krirk-kiat, Pin was never tried in any case. After years in London, he reportedly returned to Thailand earlier this year following the statutory limit of charges against him.
