PROVIDENCE, R.I. — Police in Rhode Island said early Sunday that they had a suspect in custody after a shooting that rocked the Brown University campus during final exams, leaving two people dead and nine others wounded.

Col. Oscar Perez, chief of the Providence police, confirmed at a news conference that the detained suspect was in their 30s and that authorities are not currently searching for anyone else. He declined to say where the suspect was arrested and whether the person was connected to the university.

Officers were hunting through buildings on the Ivy League campus more than two hours after the shooting erupted on the second day of final exams.

The shooting erupted Saturday afternoon in the engineering building of the Ivy League school in Providence, Rhode Island, during final exams. Hundreds of police officers had scoured the Brown University campus along with nearby neighborhoods and pored over video in pursuit of a shooter who opened fire in a classroom.

University officials initially told students and staff that a suspect was in custody, before later saying that was not the case and that police were still searching for a suspect or suspects, according to alerts issued through Brown’s emergency notification system.

The mayor said a person preliminarily thought to be involved was detained but was later determined to have no involvement.

Armed with a handgun, the shooter fired more than 40 9mm rounds, according to a law enforcement official. Authorities as of Sunday morning hadn’t recovered a gun but did recover two loaded 30-round magazines, said the official, who spoke on the condition of anonymity because they were not authorized to publicly discuss the investigation.

The shooting occurred near the Barus & Holley building, a seven-story complex that houses the university’s School of Engineering and physics department. According to the university’s website, the building includes more than 100 laboratories, dozens of classrooms and offices.

Engineering design exams were underway in the building when the shooting occurred.

Students in a nearby lab hid under desks and turned off the lights after receiving an alert about the shooting, said Chiangheng Chien, a doctoral student in engineering who was about a block away from the scene.

President Donald Trump said late in the afternoon that he has been briefed on the shooting.

“God bless the victims and the families of the victims!” he said on his social media site.

Students were urged to shelter in place as police responded to the scene, and people were told to avoid the area. A police officer warned media to take cover in vehicles because the area was still an active scene.

Officials cautioned that information remained preliminary as investigators worked to determine what had occurred.

Police were actively investigating and still gathering information from the scene, said Kristy DosReis, the chief public information officer for the city of Providence. The FBI said it was assisting in the response.

Brown is a private institution with roughly 7,300 undergraduate students and more than 3,000 graduate students.
