CHICAGO — A foul smell on Lower Wacker Drive that prompted a Fire Department investigation was believed to have been caused by a leaky garbage truck, officials said.
The smell could be detected for several blocks Tuesday morning and into the afternoon, police said.
Cops got a call about 7 a.m. that an "overpowering smell" was coming from Lower Wacker from about Lake to Washington streets, according to Officer Jose Estrada, a Chicago Police Department spokesman.
About 11 a.m., the Fire Department declared there was a hazardous materials situation in the 100 block of Lower North Wacker Drive, and said it was working with police to investigate.
The investigation was called off just before 1:30 p.m. The smell may have been caused by a garbage truck leaking as it drove on Lower Wacker, officials said.
Estrada said there were no evacuations or closures.
