Officer Edgar Delgado-Arroyo lost his powers Tuesday and was assigned to the department’s Alternate Response Section, a police spokesperson said. The unit includes officers with disciplinary issues and officers who are not medically cleared for full duty.

The Civilian Office of Police Accountability said an off-duty officer was driving in the 2600 block of West 26th Street early Oct. 4 when he encountered a group, argued with them and opened fire. The officer then drove toward the 2300 block of South Rockwell Street and fired more shots toward the original encounter, using two firearms at the same time, according to COPA.

A man was struck twice and taken to Mount Sinai Hospital in fair condition, police said.

A law enforcement source said Delgado-Arroyo went to the area after his mother told him gunfire had struck her home. The source said the officer was speaking with 911 when he was punched, then opened fire. Investigators are examining whether there was an exchange of gunfire after the officer’s initial shots, the source said.

The source described the wounded man as 24 and associated with the Satan’s Disciples street gang. Delgado-Arroyo did not respond to a request for comment.

The shooting has prompted calls from Little Village community leaders for accountability. Baltazar Enriquez, president of the Little Village Community Council, said officers who live in the neighborhood must understand they are not above the law. “We don’t need cowboys,” he said. “We need officers.”
