Seacrest Intruder Held for Felony Stalking

TMZ has learned Chidi Uzomah -- the man who showed up with a knife to see Ryan Seacrest at work today -- is now being held on felony stalking charges, and that gives Ryan some breathing room.

Law enforcement sources tell us the LAPD has decided Uzomah is a real danger to Seacrest. By holding him on felony stalking, cops have some breathing room to hold Uzomah in custody ... mainly because he was caught with a knife.
