A suspect was taken into custody after a 15-year-old boy was killed in a shooting, and another teenager was injured at Douglass Park in Chicago's North Lawndale neighborhood Thursday evening.

Chicago police said a 14-year-old boy and a 15-year-old boy were in the park in the 1500 block of South Sacramento Street around 7 p.m. when a man they did not know approached them and opened fire.

The 14-year-old was shot in the neck and the 15-year-old was shot in the back, police said. They were taken to Stroger Hospital in serious condition, where police said the 15-year-old later died.

The victims have not yet been identified.

Chicago police confirmed that a person of interest was taken into custody. The circumstances surrounding the arrest were not immediately released. 

The Chicago Park District said that in the wake of the shooting, the Douglass Park pool will be closed Friday. The fieldhouse remains open for its normal hours and programming will continue as scheduled, officials said.  Mayor Brandon Johnson, Park District Superintendent Carlos Ramirez Rosa and Ald. Monique Scott went to Douglass Park to meet with staff and campers Friday morning as well.

The park district released a statement saying in part:

"The Chicago Park District is deeply saddened by the tragic shooting that occurred at Douglass Park. We continue to cooperate with the Chicago Police Department as they conduct their active investigation. The Park District has made the decision to close Douglass Park pool today out of care and respect for the park staff and community members impacted by yesterday's events. The District is working with the Chicago Department of Public Health to offer crisis support services to the park staff and residents of the surrounding community." 

No arrests have been made in the shooting and an investigation by Area Four detectives is ongoing.
