The Tehran Police say a building has been identified in the city which has been used as a 'headquarters' to promote post-election unrest.
The Intelligence and Security Department of the Tehran Police has declared that the building -- located on Tehran's Haft-e-Tir Square -- was investigated on Monday night after a search warrant was obtained, IRNA reported.
The plotters have been arrested and are currently under investigation.
Documents found in the building indicate an ongoing plot against Iran's security was being implemented, the police said in a statement.
“After scrutinizing the building, which was the campaign office of a presidential candidate, it was discovered that the organization of illegal gatherings, the promotion of unrest, and efforts to undermine the country's security were carried out from the building,” the statement added.
Evidence has been found in the building that reveals the role of foreign elements in planning post-election unrest.
The building has in fact been a “headquarters for a psychological war against the country's security,” the police said.
The building, sources told Press TV, was used by a Mir-Hossein Mousavi election campaign.
