Weekend clashes between right-wing demonstrators and police in Budapest have injured six people and led to the detention of 15 protesters.
Police fired tear gas and water cannons on the demonstrators - many of whom were wearing swastikas and chanting anti-Semitic slogans.
Eva Tafferner, a Budapest police spokeswoman, on Sunday said: "A police car was set on fire while another was burglarised."
Five police officers and one civilian were hurt in the clashes on Saturday.
Police moved in after a group from the right-wing march attacked people leaving a separate rally by the Hungarian Democratic Charta movement and various Roma organisations.
The far right has been increasingly active in Hungary in recent years, hosting frequent protests against Ferenc Gyurcsany, the socialist prime minister.
