Six Akhil Bharatiya Vidyarthi Parishad (ABVP) members were detained after they tried to stop Rajasthan Chief Minister Ashok Gehlot's convoy and showed black flags to him when he was returning from a programme in Jaipur on Tuesday, police said.
The ABVP members showed the flags while they were protesting outside the Rajasthan University's campus over various issues, including paper leak cases.
They also tried to stop the chief minister's convoy, police said, and added that six members of the student's body were detained.
Gehlot was returning after participating in the inauguration of the Law College's student union office on the Rajasthan University's campus.
A police officer said as soon as the chief minister's convoy reached the university's main gate, some students came in front of the convoy and tried to stop it and waved black flags.
He said police immediately removed the students.
ABVP national secretary Hushiyar Singh Meena said the protest was against paper leaks and for demanding justice for the widows of three CRPF personnel killed in the 2019 Pulwama terror attack.
The widows started their protest on February 28 and also launched an indefinite hunger, demanding a change in rules so that their relatives and not just children can get government jobs on compassionate grounds. Their other demands include the construction of roads and the installation of statues of the martyrs in their villages.
However, they were removed from their protest site in the early hours of Saturday.
"The chief minister did not listen to students, then how will he listen to the common people," Meena said.
