Authorities in Fiji have detained the leaders of two opposition parties and a senior trade union official after they took part in an event critical of the country's constitution, an opposition party official says.
The leader of the National Federation Party (NFP), Biman Prasad, and a trade unionist, Attar Singh, were taken into custody over their participation in Wednesday's forum on the 2013 constitution, said NFP official Prem Singh.
"The arrest is a threat to public assembly and we don't know why they are being arrested, they are only doing their jobs," Singh said, but added that no charges had yet been made.
In a statement, the Sodelpa opposition party said its leader Sitiveni Rabuka, a former prime minister, had turned himself in to police.
Police are also holding a former politician and an official of a non-government body that organised Wednesday's event, Radio New Zealand said.
