Suspect Detained in Russian Stabbing Death That Led to Riots

Tensions grow between Russians and ethnic Muslims from Caucasus region

Moscow police on Tuesday detained 276 people who were protesting the stabbing death of an ethnic Russian man, a state news agency reported, while authorities said a suspect in the slaying had been arrested.

The killing has raised tensions between ethnic Russians and natives of the predominantly Muslim Caucasus region, many of whom have migrated to major Russian cities for work. The suspect in the slaying is from the Caucuses nation of Azerbaijan, authorities said.

The protesters had gathered Tuesday evening outside a metro station near Biryulyovo, the working-class district on the southern outskirts of the Russian capital where the stabbing occurred. Around a third of the people arrested were under 18, Deputy Director for Public Order Oleg Sigunov told the state RIA Novosti news agency.
