Sporadic incidents of violence broke out against Hindi-speaking people in six districts, most of them in north Gujarat after a 14-month old was raped in Sabarkantha district on September 28 and the arrest of a labourer hailing from Bihar for the crime.
"This violence has led to an exodus of thousands of workers and their families fearing for their lives. The BJP government in Gujarat, instead of containing this violence, is allowing these tensions to foment", stated the central committee in its statement.
Blaming the Thakor Sena, an outfit in Gujarat, the party said it is "rousing passions which are adding to the insecurity of the non-Gujaratis. This is reprehensible".
The statement said the violence was particularly against people hailing from Bihar and Uttar Pradesh, who are working in the state.
"What is happening in Gujarat is serious. Fanning hate, violence and discord is no solution for unemployment and people's economic woes", tweeted CPI (M) General Secretary Sitaram Yechury.
Since the rape incident, the Gujarat Police has intensified patrolling in areas near industrial estates and places where migrant workers stay.
