Katie Holmes 'feels like a prisoner' in her own home

Katie Holmes has told friends she feels like a "prisoner in my own home".

The former Dawson's Creek actress reportedly made the comments after her husband, Tom Cruise, announced plans to have a $1.3m security system installed at their $40m Los Angeles home - dubbed 'Cruise Castle' by friends.

A source close to the actress - who fears the star will have no personal space away from domineering Tom, said: "Because of his high profile, his children and his Scientology connections, Tom believes his family is vulnerable to potential kidnappers, stalkers and crazed fans.

"Katie will barely be able to move around her own home without being monitored by cameras and electrical devices."

Tom and Katie have almost completely rebuilt their home since they bought it in May last year.

"There will be codes and devices that only Tom will have the secret information to operate," adds the sources - who also said that Cruise, 45, learned about the high tech security systems while filming the Mission Impossible films. "It's incredible how safe this house is now.

"Katie, who led a carefree life before she met Tom, says it'll be like a prison.

"Every move she makes inside or outside their house will be recorded.

Friends of Katie, 29, are already concerned she doesn't have enough freedom from the Top Gun star, who they claim, approves her friends, her trips, screens her calls, controls her spending, and decides when and who they go out with.

"At home she would often go to a bedroom of her own and spend hours there with Suri," the friend tells Britain's Now magazine in its latest issue. "Now she says she'll feel as though there is no escape from Tom's controlling ways.

"You can escape the eyes of another person by going to a different part of the house.

"But [Katie] knows she can't escape the roving eyes of the cameras that are constantly sweeping the house."

Within the grounds of the couple's house, there's a small guard house; 24/7 cameras; floodlights activated by movement; and guard dogs. An electric fence around the grounds was, however, ruled out - but a moat inside of the compound will surround the 13,000sq ft mansion if permission is granted.

"Even that wasn't enough for Tom," adds the source. "He wanted to build a fortress that couldn't be breached - and that's what he's done."
