UPDATE Monday (10/31): Wichita police are still searching for a gunman after a weekend shooting in Old Town injured two people, one seriously.

Officers say they believe the shooting, reported early Sunday morning in the 200 block of N. Rock Island, is gang related.

Old Town Association President Jason Van Sickle says the association is working with police to install more surveillance cameras in the area and want to make sure people who commit crimes in the neighborhood are held accountable.

Wichita police say they have officers in Old Town who are familiar with known gang members and they will keep an eye on them. The city does have the power to ban certain people from Old Town.

All three Old Town shootings in 2016 are gang-related police say. The five most recent shootings in Old Town date back to 2012.

Eyewitness News heard from witnesses to the early Sunday-morning shooting in the 200 block of N. Rock Island in Old Town. Jimmy Iniguez says he was at the Pumphouse a little after midnight when he heard a loud "bang."

"I never heard a gunshot before, so I thought it was one of those big, loud surprise parties," Iniguez says. "...The next thing we know, we're looking straight ahead from out table through the bars of the club and we see all these people running out."

Iniguez says security at the Pumphouse struggled to control the crowd as everyone was leaving.

"Just the chaotic craziness of the whole night with everyone running and yelling... It was very surreal," he says.

Tyrstan Phillips says she was in line at the Pumphouse when she heard noises she thought were gunshots.

"...And my friend said, 'No, that's probably just fireworks. It's not gunshots.'" And I was thinking, 'yeah, it's gunshots,'" Phillips says. "It was pretty scary to think of something happening around here."

Police have not made any arrests in the case.

UPDATE 12:30 p.m.:

Deputy Chief Troy Livingston gave an update to a shooting that happened in Old Town early Sunday morning.

Livingston said there are four victims in the case, ranging in age from 24 to 34. The 34-year-old was shot in the chest and arm. The man also had a wound to his head, but it was not clear if that was a gunshot wound. He was taken to the hospital in good condition and is expected to recover, Livingston said.

A second person had minor injuries. He was hit by bullet fragments.

Livingston said four suspects are involved in the shooting. No arrests have been made in connection to this shooting.

Livingston said the people involved knew each other and could be connected to gangs. Also, Livingston said there is video of the altercation, which began when a fight broke out. One person fired shots.

"This is not some random event that happened down there," Livingston said. "These are two groups that knew each other."

The entire incident took place outside and did not involve any of the bars in the Old Town area. It happened in the 200 block of North Rock Island.

Livingston said police have added cameras in Old Town and hope to have more cameras in place by the winter or spring. In addition, Wichita Police have increased patrols in Old Town. Some businesses in Old Town have hired off-duty officers for extra security, Livingston said.

Livingston added Old Town businesses have been cooperative in trying to make the area a safe place. In addition, he sees a lot of promise in Old Town because of the cooperation from area businesses.

In addition, Livingston said a shooting in the 100 block of North Cleveland before the Old Town shooting is not related to this shooting.
