Crown Prince Maha Vajiralongkorn is the first in line for the Thai throne. His father, King Bhumibol Adulyadej, who is widely revered by Thais, is 86. The Thai monarchy can bestow honorary names to families in return for service under a 1915 law. Three people with the Akharaphongpreecha name were among 19 arrested in a crackdown on alleged police corruption this month in raids that netted tens of millions of dollars in assets.
