A man set himself on fire Friday morning at a CTA Blue Line stop at Damen Avenue in the Wicker Park neighborhood, causing significant Blue Line delays, officials said.

It was not immediately clear if the fire was accidental or not, Chicago Fire Department spokesman Larry Merritt said.

The man was taken in critical condition to Stroger Hospital.

Train service on the Blue Line was significantly delayed Friday, Chicago Transportation Authority officials warned.

“Forest Park- bound Blue Line trains are running w/residual delays following earlier fire department activity at Damen,” the CTA said in an alert. “Allow extra travel time.”
