A HAZMAT team responded to a suspicious package on Monday afternoon at the Mayflower Residence Hall. The package was eventually ruled to be harmless, a university statement confirmed.

Johnson County Hazardous Materials, along with the Iowa City Fire Department, responded to Mayflower around 1:50 p.m.

Students were instructed to go straight to their rooms or outside, and the mail room and front desk were blocked off.

A postal inspector analyzed the powder and an official with the Fire Department found it to be harmless food filler leaking from an envelope.

The mailroom has since been reopened, and students are now free to move in and out of the lobby.
