Baltimore police said that at least four people have been shot at or near Morgan State University.
The four were hospitalized with non-life-threatening injuries, a police spokesperson said. Johns Hopkins Bayview Medical Center was treating one patient from the attack, a spokesperson there said.
More details about the situation were not immediately clear. A shelter-in-place order for campus and the community was in effect well past midnight, but early Wednesday the university said it had been lifted and campus shuttle service would resume.
"An active investigation is currently underway related to a report of shots being fired on or near campus," the university said in an alert earlier.
"Please stay clear of the area surrounding Thurgood Marshall Hall and the Murphy Fine Arts Center and shelter in place," it said.
Just before midnight, officials said it was no longer an "active shooting" situation.
The university did not immediately respond to requests for comment.
Police on X gave the address as the 1700 block of Argonne Drive, which appears on online maps to be on the campus.
Morgan State says on its website that it is among the nation's most diverse historically Black colleges and universities and the largest in Maryland. It had around 9,100 students in last fall's semester, it said.
The FBI and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives said they were assisting Baltimore police.
