A group of overzealous Bajrang Dal activists protesting against Valentine's Day celebrations chased a brother and sister and misbehaved with them in Ujjain in Madhya Pradesh [Images].

The duo had gone to the Vikram University here for some work when the activists got after them and misbehaved with them.
"I had come to the University to drop my sister. But since her friend had not come, we were returning from the front gate.

They (activists) came towards me and they pushed and slapped me and harassed my sister also. They hit me on the head with a stick and tore my bag," the boy, who was not identified, said.

Following the incident, four Bajrang Dal activists -- Om Patidar, Suresh, Sanju and Shailendra were arrested, police sources said.

However, Mukesh Yadav, the convenor of the Ujjain Bajrang Dal told PTI that these four were not its activists as it did not indulge in such activities.

A case about the incident has been registered with the Madhav Nagar police station.
