KOLKATA: Several policemen were injured and trouble spread through Muslim dominated areas of the city on Wednesday when a mob demanding that the visa given to Bangladeshi writer Taslima Nasreen be revoked clashed with security personnel.

Crowds led by the All India Minority Forum (AIMF) fought a pitched battle with the cops and threw stones at them. Traffic on the arterial AJC Bose Road came to a halt because of the agitation as violence spread to the city's Muslim-dominated areas of Park Circus, Ripon Street and other places.

The AIMF had called for road blockade Wednesday, but suddenly demanded that Nasreen be evicted from India.
