Baltimore police issued a statement encouraging people with business at Johns Hopkins Hospital to travel to the medical complex, saying a shooting incident that erupted shortly before noon has been contained to a relatively small part of the campus. However,  officers at the scene were urging visitors to stay away because several major streets are shut down.

The Hopkins administration gave advice  that seemingly contradicted the official police statement on Twitter, urging people to stay away because of traffic problems. "Please note that traffic in the area is very congested. If you don’t need to go to East Baltimore, don’t," the statement said. Hopkins urged people to stay away from the main hospital building and the School  of  Nursing but said the public health  school was open. 

After the shooting, a man  barricaded himself  on the eighth floor of the Nelson Building after having apparently  shot a physician. Shortly bbefore 2  p.m., police reported the suspect had been shot and killed.

Before the man's death, police shut down numerous roads in the vicinity, trying up traffic and forcing the Maryland Transit Administration to reroute buses on its No. 13 route.

Terry Owens, an MTA spokesman, said an underground gate leading  from the Hopkins Metro Station to the hospital has been closed. However, he said Metro service had not been interrupted and that passengers can still leave the station via an aboveground exit.

A Sun staff member at the scene said traffic remains open on Orleans and Madison streets but that east-west streets between them, including Monument, are closed. She said Broadway apparently remains open for now but could be shut down. Wolfe Street has been closed between Madison and Orleans, she said.
