The Andheri police lathi-charged volunteers from Swabhimaan Sanghatna, an outfit floated by Narayan Rane’s son Nitesh, on Saturday for protesting outside the campuses of Chinai and MVLU Colleges in Andheri.
The colleges did not allow 156 students to take the exams because of insufficient attendance.
Eight protesters sustained injuries in the incident and have been admitted to Cooper Hospital. The police have arrested 21 people, including five students for rioting and damaging the properties of Chinai College.
On Saturday, around 40 supporters of Swabhimaan Sanghatna arrived outside the colleges to protest.
The protesters tried to get into the college and the police then lathi-charged the mob. But, the exam continued as per schedule. “Our friends have been beaten up very badly. The police should not have resorted to lathi-charge,” said a student.
Police was deployed outside the college premises since Friday after supporters of Shiv Sena and MNS vandalised the campuses.
The police had arrested 17 political activists on Friday for destroying college property.
In all, 370 students were blacklisted by college authorities for insufficient attendance. The colleges had issued three types of identity cards: red for students with attendance below 50%, yellow for those between 50% and 75% and green for the rest.
The students with green and yellow cards were permitted to attend the exam.
Amitabh Gupta, additional commissioner of police (West region), said that a case has been registered against 25 persons including the 21 who have been arrested. The process of tracking down others is on, he said.
