What a scary day for Ryan Seacrest! His alleged stalker was apprehended at the E! building this morning, where Ryan hosts his radio show!

E! identified the man as Chidi Uzomah, who had just been sentenced to 15 days in jail and 3 years probations for attacking one of Ryan's security guards outside a charity event last month! He is said to have had a knife on him this morning!

According to E!:

Uzomah, who was wielding a knife, never came close to Seacrest today. As he entered the E! lobby, security immediately recognized Uzomah from a photo that was circulated following that earlier incident. Guards confronted Uzomah and held him until LAPD arrived.

Officers came and removed him, taking him in for further questioning by the Threat Managment Unit.

Thank goodness that security worker recognized the man! I am sure Ryan is very grateful! How scary. I hope this man gets the help he needs and that Ryan remains safe.
