At least 14 policemen, including a DSP, were today injured when activists of the RJD students' wing clashed with them during a protest march, prompting the security men to baton-charge them.
Hundreds of activists of the students' wing turned violent when they were stopped by the police when they were marching to the Bihar assembly from R Block here to protest the physical removal of opposition MLAs yesterday during the monsoon session, police said.
