Multiple people were shot early Sunday at a house on Chicago's South Side, police said.
Details about the number of victims and the extent of injuries were not immediately available.
Chicago police were to hold a press conference regarding the multiple shooting victims at 6 am local time, tweeted Tom Ahern, the department's deputy director for news affairs and communications.
Police said the shooting took place on 57th and May Streets.
That location corresponds to a residential block near a park in Englewood.
A 57-year-old resident of the neighbourhood told the Chicago Tribune that he was woken up by at least five gunshots.
