A fire in Chicago's Old Town neighborhood threatened the home of the famous Second City comedy theater on Wednesday afternoon and destroyed the theater's offices. Three people were injured, including two firefighters, but none of the injuries were life-threatening.

The fire reportedly started around 1 p.m. local time. Aerial photos from the scene showed the fire coming from what looked to be a building located next door to Piper's Alley, a shopping center that houses Second City's theaters, a gym, a movie theater and a handful of other businesses.

According to DNA Info Chicago, the fire was on the top floor of an adjacent building that houses a Mexican restaurant on its bottom floor but also houses Second City's offices.
