The family at the centre of a bitcoin investment scam have said they had nothing to do with the scandal, in which Finnish investor Aarni Otava Saarimaa was allegedly defrauded out of 797 million baht's worth of cryptocurrency.
Mr Thanasit, Mr Jiratpisit and Ms Supitcha Jaravijit insisted on their innocence at a news conference in Bangkok on Monday.
Mr Jiratpisit, a 27-year-old actor, said he had no knowledge of digital currencies.
He said he did not know Mr Saarimaa in person but met the Finnish man and his girlfriend when he joined his brother, Prinya, for dinner.
Mr Jiratpisit said he knew that Mr Saarimaa was doing business with his brother and four or five other people, but he did not know the nature of the business and that he had nothing to do with it.
The actor said he has always cooperated with police officers and the court about the case, adding he had no intention of fleeing anywhere.
The Jaravijit family, according to him, has run a restaurant for almost 50 years in Si Racha district of Chon Buri. The family had operated the restaurant long before they met Mr Saarimaa.
He said his parents have been summonsed to acknowledge money laundering charges on Thursday, despite knowing nothing of such an investment.
He said although his parents have the chance to seek bail, he was afraid that their bail requests may be rejected.
"I want to say to the media that my family and I believe in the justice system and are ready to prove ourselves. We will fight the case and will not flee," the actor said.
Ms Supitcha said she had never engaged in stock trading nor opened accounts for digital assets. She said she even asked Mr Jiratpisit what bitcoin was after she was arrested.
"My father is 80 years old and he is accused of money laundering," said Ms Supitcha. "Banks and people in Chon Buri know that my father has money."
Mr Thanasit questioned why a 21-year-old Finn chose to invest such a huge sum of money in Thailand.
"The Jaravijits are not criminals. We run an ordinary business and are not law breakers," said Mr Thanasit.
He said he is waiting for Mr Prinya to be granted bail so the eldest brother would be able to speak to the public on the matter.
Asked whether he was aware that money was wired into his bank accounts, Mr Thanasit said he believed the money came from the business Mr Prinya and Mr Saarimaa were conducting together.
Meanwhile, the family's lawyer said the family's transactions will be used as evidence to fight the case. He declined to elaborate.
Mr Saarima, along with businesswoman Chonnikan Kaewkasee, complained to police in January about losing bitcoins worth 797 million baht to Mr Prinya and his group, who were supposed to invest the money in three firms last year.
