Cambodian police questioned 5 people and broke up a demonstration in Phnom Penh Tuesday.
Demonstrators marched on the streets of Phnom Penh to protest the increase of gasoline price.
The five people said they were released after about 3 hours of questioning and after they have agreed to take responsibility for any damages to people's properties.
Demonstrators accused police of violating their constitutional rights to assemble.
Police said they had to break up the protest because the protesters did not have a proper permit.
