Hundreds of Thai protesters scuffled with police and threw blue paint at them on Tuesday and, after 21 of them were arrested, chanted "release our friends!" as the royal motorcade of King Maha Vajiralongkorn swept past.

VieTrio started the show with their classical debut ‘Miracle’ followed by a series of King Adulyadej’s compositions – Love in Spring, Echo and Still On My Mind.

Thailand began circulating bank notes and coins featuring the image of new King Maha Vajiralongkorn on Friday, officials said.

Thailand's new king on Friday made his first public appearance after ascending the throne the previous day, ending a period of uncertainty since the death of his father, King Bhumibol Adulyadej, on October 13.

Crown Prince Maha Vajiralongkorn was proclaimed king of Thailand late on Thursday, opening a new chapter for the powerful monarchy in a country still mourning the death of his father.
