Sheffield Hallam University confirmed the incident was affecting students living in the Pinnacles accommodation building, which neighbours the Gateway apartments.
Pinnacles residents were initially told to stay inside last night, but they have been able to move to and from the building on Tuesday.

A spokesperson for Sheffield Hallam said: “The university is actively working with our accommodation partners to support those Sheffield Hallam students directly impacted.
“We would urge anyone affected to follow the latest advice of South Yorkshire Police during this ongoing incident."
