The Louisville, Kentucky, police department reported that a shooting occurred at a bank on Monday, leaving five people dead and six others injured.

Shortly after confirming the attack, police announced that the shooter had died without providing any other information. It wasn’t clear if the shooter was included in the five fatalities.

“We do not know exactly the circumstance of his death at this time,” Paul Humphrey, a Louisville Metro Police Department deputy chief, told reporters.

Police said they responded in minutes to reports of an attacker at about 8:30 a.m. (1230 GMT) at the Old National Bank, near Slugger Field baseball stadium in the downtown area of the city of 625,000 people.

The FBI said its agents had responded to the scene.

Kentucky Governor Andy Beshear said he was headed to Louisville in response to the shooting.
