Rome, August 6 - Rome authorities have confirmed that they have filed a complaint for damage to public property from a rally held in support of ex-premier Silvio Berlusconi following a court decision to uphold a tax-fraud sentence against the media magnate last week. Police said that traffic signals were removed on Sunday to make way for an improvised stage were Berlusconi addressed the crowd and were then put back faultily using the wrong screws and welding method. Another sign indicating a 24-hour no-parking zone that was misplaced under a non-entry area had to be moved by city workers. People of Freedom (PdL) rally organizers have been cited and could pay a fine of 4,500 euros. "A stage was never authorized for the PdL rally," Rome city officials said. PdL members have accused the city administration of being "biased without limits". "One wonders if the problem is not the event, but the ideas of the demonstrators," PdL organizers said.
