The Singapore Police Force issued an advisory yesterday warning the public against protesting over the weekend in support of the Bersih-led rally in Malaysia.
The statement said the police had been made aware of calls encouraging Malaysians living here to organise and participate in events related to the protests across the Causeway.
It reminded the public that such public assemblies without a police permit are illegal here and constitute an offence under the Public Order Act. Foreigners who break the law could have their visas or work passes terminated.
The statement added: "Foreigners working or living here have to abide by our laws. They should not import issues from their own countries into Singapore which can disturb public order."
Malaysia's Bersih plans to hold rallies in several cities this weekend to demand the resignation of Prime Minister Najib Razak.
