A 62-year-old retired professor of IIT-Delhi committed suicide by jumping from the seventh floor of the campus's main building on Saturday.
The professor, identified as Ashok Kumar Sharma, had come to the campus in the morning to meet his former colleagues.
"Initial investigation have revealed that he was fighting a court case with the IIT management," said a senior police officer, adding that Sharma had also reportedly been depressed over his health.
"We are taking the statements of his colleagues and relatives to ascertain the exact reason of the suicide," the police officer said.
Sharma was rushed to AIIMS where doctors declared him brought dead.
Sharma, a professor at the Centre for Energy Studies, had retired in December but used to visit the IIT campus regularly.
"We are also probing other angles, such as if the professor had any argument with his colleagues. We are in the process of recording the statements of the eyewitnesses," the officer added.
Sharma used to stay alone at his Dwarka residence as his wife lives in Orissa with their daughter.
"His son and another daughter are in the US. We have informed his family," the officer said.
