Frank told Los Angeles radio station KROQ that while he was outside Tom's house one of the actor's friends pressed the buzzer and the gate to the property just opened.
Frank and his three friends drove through and were waved on by security.
When they reached the top of the drive they saw Tom playing with two children on the lawn, while his fiancée Katie Holmes craddled baby Suri.
Frank said: "Suri looked cute and perfectly normal."
When Tom's security team realised the car was not meant to have been granted access they surrounded the vehicle and demanded to see some identification.
Frank explained: "The drive was too narrow to turn so once we'd gone through the gate we had to drive up to turn back.
"My friend refused to show her driving licence and said we had the right to leave.
"They kept us for about half an hour and then ordered us off the property."
So far, Suri has been kept hidden from the public eye.
Only three people claim to have seen the tot, actress Jada Pinkett Smith, Tom's ex-lover Penelope Cruz and 'King of Queens' star Leah Remini.
Both Jada and Leah are Scientologists like Tom.
However, pictures of Suri are due to be published in the autumn issue of Vanity Fair magazine.

According to Popbitch, a source from the Vanity Fair shoot of Suri Cruise says the baby looks enough like Cruise and Holmes for their parentage to be plausible, but that it is a bit of a runt, and required 21 days of photography, plus three days of digital touching-up, before the magazine and celebrity parents had a cover image they liked.

Photo agency X17 recently took photos of the couple's Los Angeles mansion on August. 10, the photos show a young woman who appears to be Katie Holmes, peering through a window in the home, and next to her, is a baby with dark hair in a bassinet, wearing only a diaper.
