Melbourne, Dec 29: Hollywood actor Tom Cruise and his wife Katie Holmes have reportedly received death threats from anti-scientology groups.

Sources have revealed that that the security around the couple and their two-year-old daughter Suri has been beefed up following the threats.

They are presently living at separate locations, and move around in bombproof vehicles.

Cruise has also been under fire for portraying Colonel Claus von Stauffenberg - who was at the centre of the 1944 plot by Nazi officers to assassinate Adolf Hitler - in his new film `Valkyrie'.

Last week, he also attended the Los Angeles premiere of the movie, which was targeted by protesters from the anti-Scientology group Anonymous.

"Tom is terrified. He doesn't feel safe anywhere," Daily Telegraph quoted the source as telling The Mail.

"The threats are perceived to be so great that the FBI has been alerted," the source added. (ANI)
