A burglar smashed through locked glass showcases at Mile High Comics and cut himself while stealing 14 comic books worth more than $42,000.

He then tried to clean up the blood with Windex and toilet bowl cleaner.

Denver police are investigating the burglary at 4600 N. Jason St. that occurred early Sunday where a man — shown in surveillance footage — forced entry into the store and stole items, according to the Denver Police Department.
