( BBC ) - Police in Denmark have arrested more than 400 people in clashes in the capital, Copenhagen.
They used teargas against thousands of young demonstrators protesting against the closure of a youth centre (Ungdomshuset) earlier in the year.
The protesters had tried unsuccessfully to occupy a different building.
A Copenhagen police spokesman said 437 people had been arrested - a record number - but that he expected most would be freed overnight.
"It started out as a peaceful demonstration but then there was more and more violence and the riots against the police started," spokesman Flemming Munch told the AFP news agency.
Police fired tear gas at the demonstrators after they threw smoke bombs, tried to break through police barriers and climb over police cars.
No injuries were reported.
Organisers of the demonstration said as many as 4,000 people took part.
Left-wing activists had occupied the youth centre, in Copenhagen's Noerrebro district, since 1982.
But the building was sold by the city in 2000 to a Christian group.
Squatters were evicted in March 2007, which led to violent street clashes and hundreds of arrests.
The youth centre was later demolished.
