The actor's security team dashed to the property when it was alerted to the fact workers on Pitt's new home had discovered two members of a crew from US cable TV network E! Entertainment on his property.
Sources tell website TMZ.com the alleged trespassers were spotted walking up a dirt driveway at the back of Pitt's home after unchaining a gate.
They were allegedly filming the exterior of Pitt's craftsman house when they were spotted and detained as security guards attempted to confiscate a camera.
But an E! spokesperson insists the sourced account of events is not totally true.
The spokesman says, "From our initial investigation, that is not how the events occurred."
A source for the TROY star insists Pitt intends to press criminal trespassing charges.
