A CTA bus driver was attacked with pepper spray Tuesday while driving in Lincoln Park on the North Side.

He was driving about 7:42 a.m. in the 1900 block of North Clark Street when an exiting passenger used profanity before spraying his face with a chemical irritant, Chicago police said.

The 56-year-old man was taken to St. Joseph Hospital in good condition, police said.

He told investigators there was no previous altercation between him and the suspect, who was described as a man in his 60s, police said.

The Chicago Transit Authority said the victim was a CTA bus driver, and that the CTA is assisting Chicago police in their investigation.
