Students in the eastern Pakistani city of Lahore have continued their protests after reports of a rape on a college campus.

Tuesday’s demonstrations, including staging an antiharassment rally, came a day after protests were held on two college campuses, which the provincial government has since shut down. At least 28 students were injured in clashes with police on Monday.

Protests erupted in Lahore after reports spread online that a student was raped by a security guard at a Punjab College for Women campus.

The incident was first shared on social media over the weekend. Varying accounts state that the rape took place on Thursday or Friday evening in a campus basement.

According to the college, the victim has not been identified because no one has come forward to lodge a formal complaint, adding that no incident has been reported to the police and false information has spread online.

On Monday, police also initially dismissed the online reports as “false” but later said a guard had been accused of rape, was in custody and an investigation was underway.
