Demanding withdrawal of criminal cases, students under the banner of Punjab Students Union staged a protest in Punjabi University campus on Wednesday.
The protesters condemned the despotic attitude of state government and burnt the effigy of Punjab chief minister Parkash Singh Badal.
On September 13, the local police registered a case against 12 students after they tried to barge into deputy commissioner's office following which the police resorted to cane-charge to disperse students.
"The police have registered bogus case against 12 students including two girls for damaging public property and obstructing public servant in discharging their duty," said Beant Singh, state secretary of union.
The union is demanding free education for Dalit students, scholarships for minority students, free education for girls and various other demands.
"We will launch a massive protest if criminal cases are not withdrawn and our demands are not fulfilled," he said.
Democratic Students Organisation, Democratic Lawyers Association and Human Right Security Association also extended their support to PSU.
