Thiruvananthapuram: A crude bomb was hurled at a BJP office in the heart of the city here, with the party alleging that CPI-M workers were behind the attack.
No one was injured in the incident, police said.
The incident occurred around midnight last night, shortly after BJP state president Kummanam Rajasekharan had left the office for Kozhikode, where preparations are on for the three-day National Executive and Council meeting from September 23 which is being attended by senior party leaders and Prime Minister Narendra Modi, party sources said.
At least four workers were on the top floor of the building, housing the office, when the bomb was hurled.
Though no one was injured, glass panes of the main entrance door were damaged in the incident, Thiruvananthapuram City Police Commissioner S Sparjan Kumar told media.
The incident comes close on the heels of a series of sporadic clashes between CPI-M and BJP workers in the past few months in northern Kannur district.
