Police are responding to a “very active situation” amid reports of a series of shootings at a shopping mall in Milwaukee, Wisconsin.
Reports suggest a number of people have been injured in the incident at Mayfair Mall in Wauwatosa.
Photos show a heavy armed police presence at the scene.
The mall was the site of a February shooting in which a police officer, Joseph Mensah, shot and killed Alvin Cole, a black 17-year-old.
Officers claimed Cole was fleeing from police. Mensah, who is also black, said he shot Cole because Cole pointed a gun at him.
The mall has been the target of sporadic protests over several months in the wake of the shooting.
