A manhunt is continuing for the suspect after the shooting at Brown University, in Rhode Island.

The Providence-based university remained in lockdown hours after the attack in a building where students were taking exams.

Local mayor Brett Smiley said late yesterday that officials do not believe there is any “specific ongoing threat” from the suspect.

But police and other law enforcement agencies, with 400 personnel deployed, are searching the area.

A shelter-in-place order for the campus and surrounding neighbourhood remains in place.

“The shelter-in-place allows [law enforcement] to do their
work in the first phase of the investigation,” Smiley said. 

Streets around the campus were packed with emergency
vehicles and security was heightened around the city as the gunman, who has not yet been
identified, was sought.

Agents from the Federal Bureau of
Investigation and the Bureau of Alcohol, Tobacco, Firearms and
Explosives are working with local and state police on the
investigation.Â
