In a post on Twitter, the musician said he had a panic attack at work after the incident.
“I was working at the office at the time and was in a meeting with a manager, we were talking about our new album, ‘The Dream.'”
I woke up at 6am and went into my car to get ready.
I got into my Volvo and drove to the building to get in there and I went to my meeting and there was an officer outside who was asking me what I was doing there.
“He said to me, ‘you’re on the way to your meeting.
You’re on your way to the studio.
You have to be in there in 15 minutes.
You need to go now.'”
