(CHICAGO) Shots were fired at Chicago Police officers Tuesday night in the South Side Auburn Gresham neighborhood, marking at least the fourth time officers have come under fire in about a week.

About 7:30 p.m. shots were fired at officers in the 1100 block of West 86th Street, police said. No one was hurt, and a person of interest was being questioned, police said.

Last Friday, five people were arrested after a five-hour standoff with a police SWAT team that started when someone opened fire on a CPD supervisor in the South Chicago neighborhood.

Two men have been charged with shooting at CPD and FBI investigators Nov. 28 on the Southwest Side, and another accused of shooting at officers after shooting a pregnant woman in West Garfield Park was fatally shot by police Nov. 27.
