A man who fired shots Monday outside a Department of Veterans Affairs hospital in Chicago is now in police custody, according to authorities.
The man began shooting outside the Jesse Brown VA Medical Center before 3 p.m. and then tried to enter the lobby, Chicago Police Department spokesman Tom Ahern told The Associated Press. Ahern said security officers apprehended the man near the hospital entrance.
No one was injured and authorities recovered a rifle that the man is believed to have used, the AP reported.
Investigators haven't determined what led to the gunfire or who the man might have been targeting, Ahern said.
A witness at the scene told the Chicago Tribune that the man walked up to the building and started shooting. As he appeared to be reloading, the witness said a car tried to hit him, so he ran into the building.
Chicago police and FBI agents, which announced on Twitter that they also responded to the shooting incident, are expected to release more information during an upcoming news conference.
Located on Chicago's West Side, the VA facility has 200 beds and provides care to about 62,000 military veterans in five counties.
