The former JNUSU president escaped unhurt but his driver sustained injuries in the attack that happened in presence of policemen, reports M I Khan from Patna.
The convoy of Communist Party of India leader Kanhaiya Kumar, who is on a tour of Bihar -- campaigning against the Citizenship (Amendment) Act, National Population Register and National Register of Citizens -- was attacked in Supaul district on Wednesday evening.
The former Jawaharlal Nehru University Students' Union president escaped unhurt in the attack by a group of youths who were shouting pro-CAA/NRC slogans.
This is the second attack on Kanhaiya's 'Jana Gana Mana Yatra' within a week in the state. Last week, his convoy was attacked in Chhapra of Saran district.
An activist who is part of the yatra said, "Youngsters shouting slogans attacked vehicles, pelted stones and tried to stop us near a busy market, not far away from the residence of district magistrate in Supaul town."
The driver of Kanhaiya's vehicle sustained a head injury and was rushed to a nearby hospital for treatment.
Two other people were also injured in the attack.
"Three vehicles were damaged by attackers and three members have sustained injuries," Chandra Kanta of Samvidhan Bachao Morcha said.
"The convoy has left for its next destination. Investigation is on to identify and nab the culprits," Sudhir Kumar Porika, Superintendent of the Special Task Force, who is holding the additional charge of Supaul, said about the attack.
The yatra was earlier attacked on February 1 near Kopa police station in Chhapra.
"Glasses of five vehicles were damaged in that attack and some people sustained injuries," Kanta said.
Kanhaiya was then on way to Chhapra from Siwan to address a public meeting.
The yatra was attacked in presence of local policemen who were supposed to provide security to the same.
The 'Jan Gan Man Yatra', which began on January 30, had a rough start when Kanhaiya was told by the police in West Champaran district that permission for his first scheduled rally was withdrawn at the eleventh hour.
Congress MLA Shakil Ahmad Khan, who has been accompanying the CPI leader since the commencement of the tour, blamed 'negligence on part of the police and the administration' for Wednesday's incident.
"It is a small town. The spot where the attack took place is less than a kilometer from the collector's residence. Police personnel and officials of the district administration were deployed.
"Still the miscreants hurled stones, raised slogans and managed to flee taking advantage of the dark," Khan alleged.
"I have telephoned the director general of police seeking intervention from the highest level. Our yatra is to continue for the next few weeks.
"Already we are on the move, having left Supaul for Saharsa where Kanhaiya's next rally is scheduled on Thursday. We hope the law and order machinery would rise to the occasion," the MLA added.
CPI state secretary Satya Narayan Singh issued a statement in Patna, strongly condemning the incident and demanding stern action against the culprits and 'guilty police officials'.
The state-wide tour is being conducted under the banner of 'Joint Forum Against NPR/NRC/CAA'.
It is scheduled to conclude with a rally at Gandhi Maidan in Patna later this month.
