Three of the five Akhil Bhartiya Vidyarthi Parishad activists accused in connection with the death of a Ujjain professor were arrested on Monday, the police have said.

The three -- identified as Satish Sharma, Parmanand Bhargav and Gagan Singh Raghuvanshi -- were arrested on Monday morning in connection with the incident that happened on August 26.

Professors H S Sabharwal and M L Nath had cancelled the Madhav College students' union elections following allegations of irregularities, leading to a fight with the activists.

Two others, Sudhir Yadav and Hemant Dubey, were arrested on Sunday, the police said.

Sabharwal's death prompted a series of allegations and counter allegations between the National Students Union of India [ Images ] and ABVP workers, sources said.

An autopsy report confirmed that two of Sabharwal's ribs were broken and that his lungs had bled, causing his death.

A magisterial probe was ordered into the incident, while three cases were registered for Sabharwal's murder and that for manhandling of Nath.
