Parinya Jaravijit, a key suspect in an alleged Bt800-million bitcoin investment scam, was arrested on Thursday night at Suvarnabhumi Airport when he arrived back in Thailand.

Police will this week summon witnesses to provide additional information for the investigation into an alleged Bt800-million bitcoin investment scam, while key suspect Parinya Jaravijit has sent a letter through his lawyer requesting postponement of the date for him to hear the charge of colluding in fraud, the deputy chief of the Crime Suppression Division (CSD) said on Tuesday.
