The SFI observed a student strike on Thursday, to protest the death of its leader Sudipta Gupta, setting up roadblocks in West Bengal, including the capital.
SFI members blocked busy roads in the metropolis and other parts of the state for 15 minutes at 11 am. The blockade was peaceful, police sources said.
Several schools and colleges remained open ignoring the SFI's call for a student strike.
The CPI(M)'s 12-hour general strike at Garia and Tollygunge in the southern suburbs, where Gupta lived and studied during his school and college days, was peaceful.
Gupta, a 22-year-old MA student at the Rabindra Bharati University, died while being taken to jail following a law violation programme by the SFI on Tuesday.
