While police denied any such incident, mediamen deployed outside Bachchan's bungalow anticipating trouble in the wake of clashes between the MNS and Samajwadi Party (SP) supporters on Sunday said they heard verbal abuses being hurled by the duo and also saw a bottle being thrown by them.

Security was already stepped up at Bachchan's house 'Prateeksha' in Juhu following the MNS chief Raj Thackeray's attack on the superstar for preferring Uttar Pradesh over Maharashtra for opening a girls' college.

Senior police inspector Deepak Katdare of the nearby Juhu police station, who denied the attack, said: "Apart from the private security guards posted there, we had also deployed our own men at the spot and no such incident has been observed there during the night."

However, a mediaperson present at the spot said: "At around 1:30 am, some cameramen, who were posted outside the bungalow anticipating trouble, heard the abuses and also saw a bottle being thrown at the direction of bungalow."

Earlier in the night, SP leader Amar Singh had lodged an FIR against Thackeray and others in South Mumbai's Azad Maidan police station regarding the incident of protest by MNS activists during his press conference on Saturday.
