Two petrol bombs were hurled at the CPI (M) office at 100 feet road in Coimbatore on Saturday morning by unknown people.
There was minor damage to a car but no casualties were reported.
A complaint has been filed at the Gandhipuram police station in Kattoor and investigation is going on in the case.
The incident happened at around 6am. There are no CCTV cameras in the office but the police are checking the CCTV footage of the nearby houses to know more about the incident.
Jayabal, CPI (M) District Acting Committee member, addressing the media said that they suspect Hindutva groups to be behind this act.
‚ÄúToday morning, we saw smoke coming out of the car. We immediately informed the police. We suspect fundamentalists, particularly RSS group have done this. They have been attacking everyone who protests against their policies but we are not going to be cowed down, we will continue to protest,‚ÄĚ he said.
The CPI (M) members also said that they had conducted a meeting condemning the attack on CPI (M) leader Sitaram Yechury in Coimbatore. They suspect that this could be the reason for the attack on the office on Saturday morning as they were asked to stop the meeting t by Hindutva groups.
The forensic department visited the place and took samples of the petrol bomb. Deputy Commissioner, Law and Order of Coimbatore also visited the area and promised to take action against the culprits.
