Amitabh Bachchan says an unknown person has been sending derogatory and abusive material on his blog and mobile phone. After enduring it for months, he has filed a police complaint.

"There is a serious effort by a member that writes and comments on this blog to use language and expression that is abusive, filthy and utterly disgusting, " Big B wrote on his bigb.bigadda.com.

"I have brought this to the notice of the authorities and (sought) corrective measures to see none of the stuff that comes from this foul mouthed individual shall ever be allowed on this platform. Any further attempt from this person shall now be under legal cyber space action, now very prominently activated in the country.

"This blog, this platform, this home for our extended family members is a sacred and revered destination and any attempt to defile it shall be dealt with in the most severe manner, " he added.

Amitabh further revealed he is also receiving derogatory messages on his phone.

"Further more. This individual has been sending me the most unprintable abuse on SMS on my phone. I have, after great tolerance for months, reported the matter to the police and they will be taking serious punitive action, not just in my country but in the country of the origin of these missives."
