The police raided the DAP Perak headquarters in Ipoh today after a report was lodged by an Umno member over the opposition party's campaign against Islamic state as declared by the prime minister last September.

According to DAP national chairperson Lim Kit Siang, the raiding team comprising 20 policemen searched the premises for an hour and confiscated some 5,000 copies of campaign leaflets.

The opposition leader said the police had crossed an "important line" to stay above political fray and not allow themselves to be used by ruling political parties.

"Would the police immediately raid the Umno headquarters and state premises if the DAP lodges police reports against them?" asked Lim in a press statement.

"The unprecedented raid of opposition party premises with an excessive show of force will only feed the national and international scandal about the lack of professionalism of the Malaysian police," he added.
