Nepal's police have arrested some 50 journalists who were protesting press restrictions imposed after King Gyanendra dismissed the government and assumed absolute power.
The journalists had gathered near the main government offices in downtown Kathmandu and called on the royal government to allow FM radio stations to broadcast news.
The trouble began when they tried to break through a line of police who were blocking them from leaving an exhibition center where they had been protesting.
The royal government has declared that many of the streets near the royal palace are restricted areas where demonstrations are not allowed.
Dozens of reporters have been arrested since King Gyanendra took power, and some of them are still behind bars.
There is a ban on criticism of the king, and also on any independent reporting on the country's Maoist insurgency.
