"The UP administration should file cases against Balyan and others for inciting communal hatred. The state government should deal firmly with all the elements trying to incite communal passions and provoke violence," party politburo said in a statement.
According to media reports, Balyan had on Monday sought a probe to ascertain who had eaten the meat recovered from outside the residence of 50-year-old Mohammad Akhlaq, who was lynched by a mob in Dadri's Bishada village for allegedly consuming beef in September last year.
CPI(M) questioned the timing of Balyan's "provocative" statement and alleged that it was part of BJP's "wider game plan" aimed at polarising the state on communal lines ahead of the assembly polls next year.
"...These statements are being made with an intention of stoking communal tensions and are part of wider game plan of BJP to create communal polarization in UP before assembly polls next year...There should be no laxity in prosecuting all those accused in the Akhlaq murder case," the statement said.
