Katie Holmes reportedly fears she can’t take one step without a Scientology goon following her every move in a heavy- handed intimidation attempt.

The pretty actress last night was holed up in her Chelsea pad — terrified that soon-to-be-ex-hubby Tom Cruise might kidnap their little girl, law-enforcement sources said, Fox News reproted.

Holmes told another building resident of her abduction fear — and that neighbor called police on Friday, sources said.

"[Scientologists] are professionals at pressuring people to be quiet. That’s why she did this [filed for divorce] in secret"

Holmes, who filed for divorce from superstar Scientologist actor Cruise last week, knew this was coming, the sources said.

“Katie saw all the pressure. They [Scientologists] are professionals at pressuring people to be quiet,” said a friend of the actress after her bombshell divorce filing in Manhattan last week. “That’s why she did this [filed for divorce] in secret.”

A team of beefy armed men parked themselves in a white Cadillac Escalade outside Holmes’ place all day yesterday, snapping pictures of people outside the building and demanding to know who they were.

Cops finally pulled up in a marked NYPD squad car behind the SUV and checked out its Tennessee license plates. The officers said they were acting on complaints of “suspicious activity in a white Escalade” but did not elaborate. They spent about 15 minutes eyeing the SUV before leaving. At least two of the five men sitting in the SUV were clearly packing heat. When asked who they worked for, one wisecracked: “We’re waiting for a bus.”

A Holmes rep has said the mystery men weren’t with the actress.
