'Person of interest' detained over Brown University shooting, official says

A person of interest has been detained in connection with a US shooting at Brown University that left two people dead, an official said.

Nine others were injured when a gunman opened fire at the university in Providence on Saturday.

An earlier order for people on the Brown campus and surrounding areas to shelter has been lifted, but police are still present.

Of those injured, medics said one person was in a critical condition, six were "critical but stable" and two others were less severely hurt.

The gunman opened fire in a classroom at around 16:00 local time (21:00 GMT) on Saturday at the Holley engineering building at the eastern end of Brown's campus, according to officials.

The identities of those killed or injured have not yet been released, but Brown University President Christina Paxson told reporters in a press briefing on Saturday that all the victims, including those killed and wounded, were students.

Police had earlier released CCTV footage of a male suspect walking away from the scene wearing all black clothing. Officers said a firearm was not found in a sweep of the building.
