Haz Mat Incident - 500 block of 14th Ave SE. Unconfirmed report of ricin. Crews are evacuating the building and isolating the affected area. One resident taken to an area hospital prior to MFD arrival. — Minneapolis Fire (@MinneapolisFire) May 7, 2019

The Minneapolis Police Department said Tuesday night that a hazmat team entered the apartment and neutralized the area. A substance that was found in the apartment was taken to the Minnesota Health Laboratory, where it will be identified.

The police department said FBI hazmat personnel are working with Minneapolis first responders.

A cleanup and investigation are expected to continue into the evening.

According to the Minneapolis police spokesperson John Elder, the building has been opened back up and tenants are allowed to return as of 9 p.m. However, the affected apartment will continue to be blocked off from the public.

Students on scene said they didn't see or smell anything unusual, and thought it was just a routine fire drill or somebody had possibly pulled a fire alarm.
