Unidentified persons pelted stones at the house of newly elected RSP MP N K Premachandran, damaging windowpanes, but none were injured as he and his family are in Delhi, police said today.
Locals told police that a group of 10 persons came to the spot late yesterday night, pelted stones and also pasted posters, accusing the MP of 'deceiving' the Left Democratic Front (LDF) for power and position.
Revolutionary Socialist Party (RSP) had severed its ties with the Communist Party of India (Marxist) led LDF on the eve of the April 10 Lok Sabha polls and became a parter in the ruling Congress-led United Democratic Front (UDF).
Premachandran had defeated CPI(M) politburo member and former state Minister M A Baby in the polls.
RSP is stated to merge with RSP (Bolshevik), which is already a partner in the ruling front, at a "re-unification" conference here on June 10.
RSP state secretary A A Azeez and State Labour Minister and leader of RSP(B) Shibu Baby John visited the house and requested the state government to take serious note of the incident.
