Two motor-cycle borne youths threw glass bottles at actor Amitabh Bachchan's [Images] residence in the wee hours of Monday, in the wake of Raj Thackeray-led Maharashtra Navanirman Sena attacking the superstar for alleged negligence of Maharashtra.

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

Security was stepped up at Bachchan's residence 'Prateeksha' in Juhu, following 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 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, 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 protests by MNS activists during his press conference on Saturday.

A couple of theatres staging Bhojpuri films outside the metropolis were attacked and five cars were damaged during Sunday's violence. The police had arrested 15 MNS and five SP activists after the clashes.
