Two men escorted out of the New Humboldt Inn after an argument early Thursday morning later returned and shot the tavern’s security guard and two other individuals, according to the bar’s owner and authorities.

Lakeemen Jones, the security guard, suffered wounds to the upper body while Romone Anderson suffered bullet wounds to the right hip and right elbow, and Douglas Young suffered a wound to his right hip, Northeast District police said. All were treated and released from Erie County Medical Center.

Zenith Jackson, the main owner of the bar, said he was told that Jones, 37, had ejected the men who were arguing at about 2:30 a.m. and then locked the door to the establishment.

“I guess they went to their car and got a gun. Lakeemen had locked the door. They then knocked on the door, and he opened it. That’s when the shooting happened,” Jackson said.

A surveillance camera video has been turned over to police, and police also recovered seven 9 mm shell casings.

Jackson said he has owned the New Humboldt Inn, at Humboldt Parkway and East Delavan Avenue, since 1996 and this is the first time anyone has been wounded by gunfire inside the establishment that he can recall.

In July 2011, a man was shot and killed across the street from the bar. Two other men were wounded.

“From what we understand, there had been an argument earlier in the evening at another bar in downtown, and it carried over when they ran into each other later in the night,” Jackson said.

Following that incident, Jackson said he met with Northeast District police officials to discuss ways to avoid future problems, and it was decided he would start closing the bar at 3 a.m. instead of it current closing time of 4 a.m.

“We don’t want to get the riff-raff,” he said.

The New Humboldt Inn, he added, has employed an armed security guard for years.

A search for the shooters was continuing, and police appealed to the public for assistance. Witnesses were asked to call the confidential tip line at 847-2255.
