Reed Harris, the former owner of the WEC and current vice president of athlete development for the UFC, was part of the van that was attacked by Conor McGregor and his fight team Thursday inside the Barclays Center in Brooklyn.

Harris was sitting near Michael Chiesa when an item hit the window, shattering it and sending glass everywhere. Chiesa suffered several cuts and was sent to the hospital. UFC officials later elected to cancel his planned fight with Anthony Pettis entirely.

“It was the scariest thing I’ve ever been through,” Harris posted on Twitter. “Trapped in the bus while they are throwing hand trucks, chairs and even a bike rack through the windows. When the hand truck (went) threw the window and hit Chiesa in the head and he started gushing blood. Yes. I thought we were in big trouble.

“I’ve been in dozens of scuffles in UFC. Never once I was scared. This time was different.”

McGregor is being sought for questioning and is banned from the building for both weigh-ins and the UFC 223 event Saturday night. It is unknown if he will face further punishment from the UFC for his role.

Artem Lobov, a teammate and close friend, had his fight with Alex Caceres pulled for his involvement in the incident. He is also banned from the premises.

It is believed that McGregor was seeking out Khabib Nurmagomedov, who confronted Lobov in the fighter hotel earlier this week while he was alone.
