Buildings on Salford University's Peel Park campus have been evacuated.
It comes after Monday night's suicide bombing at Manchester Arena that killed 22 people and injured 59 others.
The university said in a tweet: "Buildings being evacuated on Peel Park campus; New Adelphi, Lady Hale and Clifford Whitworth library. Please follow instructions from staff."
Student Kieran Stockton told The Independent: "When I got onto the walkway they were evacuating must have been 100 or 200 students out of the back of the library, which is never used so whatever has been found is at the front of it."
The university said in a statement: "Emergency services have been called to Salford University’s Peel Park campus to investigate a suspicious package left under a bench.
"The university has evacuated the main library, the New Adelphi arts building and the Lady Hale (Salford business school) building, as a precautionary measure.
"Police are currently on site with a sniffer dog en route."
Students have since been given the all-clear.
Police confirmed on Tuesday evening they suspected the bomber was 22-year-old Salman Abedi.
Reports suggested he was the son of Libyan refugees who fled Colonel Gadaffi's regime.
