Thailand protesters drench police headquarters with paint

Angered by the government's decision to reject a constitutional reform proposal - a key demand of protesters - and alleged police violence, demonstrators hurled buckets of colourful paint and sprayed graffiti on the Royal Thai Police headquarters' building facade.

Police barricaded themselves inside the station and did not intervene.

Thailand has been rocked by student-led protests for months, with protesters demanding constitutional reforms, the removal of the country's Prime Minister and changes to the monarchy.
