Russian police shut down a nationalist rally promoting a healthy lifestyle in the Kaliningrad region after mistaking the weekend gathering for a gay pride parade, according to a Baltic news agency.

The two dozen activists -- hoisting a black, yellow and white banner of imperial Russia -- had taken to the streets in Sovetsk to promote jogging, according to the news site 40161.ru, which covers the former Soviet enclave.

But they were quickly met by police who escorted them to the Interior Ministry.

Police told them that a "vigilant citizen" had tipped off authorities in an anonymous phone call that the unsanctioned gathering was a gay pride parade.

It is not the first time the nationalists have run afoul of the law, RIA Novosti notes. [color=gold]Their jogging rally in Moscow's Izamilovsky Park last February ended with most participants fined for jaywalking, the news agency reports.[/color]
