Vivek Oberoi called a press conference on Tuesday where he claimed he had received threats from Salman Khan.
Salman, he alleged, had threatened to 'kill' him.
The actor said Salman called him on his cell phone throughout the night of March 29, accusing him of "physical relationships with Aishwarya Rai, Diya Mirza, Rani Mukherjee and Somy Ali, whom I met some seven years ago."
Oberoi said Salman was drunk, abusive and threatened to come to his house and assault him. Salman called him 41 times that night, he added.
The actor had to fly down to Chennai on March 30. He said his friend Kshitij Mehta called and asked him not to return to Mumbai, as Salman's bodyguards were enquiring about his whereabouts.
Oberoi then decided to return immediately to Mumbai and take matters into his hands. Salman, he said, was mentally disturbed and needed help.
He now plans to lodge a case with the police against Salman.
