(CNN) — One person was killed in Tuesday's shooting at an electrical engineering building at Purdue University, campus police Chief John Cox told reporters.
The shooting was reported around noon ET at an electrical engineering building on the northeast side of the West Lafayette campus of the Indiana school, Purdue spokeswoman Liz Evans told CNN's Wolf Blitzer.
Police told school officials that one person was in custody Tuesday afternoon, said Evans, who added that she didn't know whether anyone was injured.
The school sent text messages to students about the shooting report, asking them to take shelter where they were. That request was lifted by 1:30 p.m., though the electrical engineering building still was closed so police could investigate, Evans said.
"The rest of campus is open" and classes were under way, Evans said.
A Purdue student, Brad Glusvewski, told CNN that the university warned students of the reported shooting by text message around 12:20 p.m. ET. Glusvewski, 24, said he and about 15 other people were staying inside the on-campus building where they were when they heard the report.
The university had more than 30,000 undergraduate students last school year.
CNN first learned about the shooting report on Twitter.
