An unidentified person allegedly sent an e-mail to a private news channel warning of an explosion at actor Amitabh Bachchan's [Images] residence Jalsa in suburban Juhu, Mumbai, forcing the police to carry out a thorough search of the premises.

The search was carried out for an hour from 1500 hours on Wednesday.

"I received a call from the news channel saying that they have received an e-mail saying a bomb would go off at Jalsa at 4.30 pm. A team from the Bomb Detection and Disposal Squad was immediately rushed to the spot, but no explosive material was found," Additional Commissioner of Police (West Region) Archana Tyagi told PTI.

She, however, did not reveal the name of the channel, which received the e-mail.

All the necessary precautions were taken during the search without disrupting the traffic movement on the busy road opposite the bungalow, the police said.

It was not immediately known whether the superstar was in his residence when it was searched.

"I have asked them (the news channel) to forward the e-mail to me. We will definitely trace its sender," Tyagi added.
