Pune police yesterday raided the houses of prominent Left-wing activists across several states as part of a probe into anti-Dalit violence at Koregaon-Bhima village near Pune after the Elgar Parishad conclave on December 31 last year. Telugu poet Varavara Rao, activists Vernon Gonsalves and Arun Farreira, trade union activist Sudha Bharadwaj and civil liberties activist Gautam Navalakha were arrested following the raids. The action has come in for a strong criticism from opposition parties and others who have termed it an attempt to stifle dissent.
