Protesters tried to storm a Government department to mark the first anniversary of the clearance of Europe's largest traveller site in Essex.
About 100 people still angered by the eviction of travellers from Dale Farm in Crays Hill a year ago staged a demonstration outside the Department for Communities and Local Government (DCLG) offices in central London.
Some demonstrators attempted to gain entry into the building to "evict" the department's secretary Eric Pickles but were restrained by police.
The protest marked a year since the violent scenes during the £7 million clearance of Dale Farm as travellers and protesters clashed with bailiffs and police.
