The man at the heart of the bomb threat that forced evacuations in downtown Kansas City is well known to Kansas City Chiefs fans as “helmet man.”

The Kansas City Star reports calling the suspect, tentatively identified as Wahed Moharam.

A man identifying himself as Wahed said “everything is OK.”

He added: “And everything mistake. Everything mistake. I didn’t have any bad thing anyway. Everything is just…thank you and God bless you and I’m OK.”

The newspaper reports Waheed’s tickets were revoked out of safety concerns in 2003 because he was in the federal witness protection program for testifying in the first World Trade Center bombing.

Sources told the Star the man created a disturbance inside the Fletcher Daniels building at 615 E. 13th Street by yelling something to the effect of: “Why am I on the terrorist watch list?”

That prompted deployment of FBI bomb dogs, which reportedly registered a “hit” on the man’s car.
