PROVIDENCE: Police in the United States on Sunday detained a “person of interest” in relation to a shooting at Brown University that left two people dead and nine others wounded, Providence Mayor Brett Smiley said.

Speaking alongside the mayor at a news conference, Police Col. Oscar Perez said the person was detained “earlier this morning” and law enforcement officers are “not at this point” looking for anyone else in relation to the attack.

A gunman opened fire at the Ivy League school just after 4 p.m. (2100 GMT) on Saturday, with the school sending out an alert of “an active shooter near Barus and Holley Engineering.”

Two exams had been scheduled at the time.

Of the nine wounded one is in critical condition, seven are in stable condition and one has been discharged, Smiley said.
