Chidi Uzomah, Ryan Seacrest Stalker, Arrested with Knife Inside E! Building

An apparently dangerous stalker of Ryan Seacrest, Chidi Uzomah, was arrested inside the E! building where Ryan shoots his daily TV show earlier this morning.

Uzomah was arrested at 9:40 a.m. PDT today, after showing up at E! offices and asking to see Ryan Seacrest. He was armed with a knife when he showed up.

Sources say he is the same man who attacked Ryan's security guard last month outside an Orange County hospital. In that incident, he had a knife as well.

Uzomah pleaded guilty to three misdemeanors for the prior incident. The judge placed him on three years probation, ordering him to stay away from Ryan.

Apparently that didn't work.

He was detained by LAPD the in the lobby of the E! building after a security guard, who was aware of who Chidi Uzomah was, called them after he came in.

An armed Chidi Uzomah came looking for Ryan Seacrest today. Scary.

Ryan Seacrest was in the building at the time Uzomah entered, although fortunately the deranged lunatic never got within sight of the American Idol host.

According to TMZ, the hardest working man in Hollywood and his staff have been asking prosecutors for weeks to take swift action against the alleged wacko.

Earlier this month, Uzomah, unaware that his target works out of E! offices in L.A., showed up at KIIS-FM in Burbank, Calif., on the hunt for Ryan Seacrest.

The Burbank police were called but no arrest was made.

Ryan's people called the Orange County D.A.'s office immediately after the KIIS incident, asking prosecutors to violate Uzomah's probation and put in place a criminal protective order. They fear he poses danger and should be locked up.

Not a hard sell after today's frightening encounter.
