One person is dead and three others are injured after a shooting at an unlicensed nightclub in North Houston, according to the Harris County Sheriff's Office.

Upon arriving, wrote Gonzalez, officials found three injured men. Two had gunshot wounds, and a third may have been assaulted. The three men were hospitalized and are in serious condition. Gonzalez wrote that a fourth man found at the scene was taken to a hospital, where he was pronounced dead.

Assistant Chief Luis Menendez-Sierra said officers discovered a "very hectic scene" with a large crowd of people running out of a makeshift club.

"We are assuring the public that we are going to put all our resources in finding out what happened here tonight," said Assistant Chief Luis Menendez-Sierra.

Police in Houston say two teens were killed and four were injured — including a 13-year-old girl — in a shooting at a makeshift club.

A shooting early Sunday morning at an unlicensed after-hours bar left one person dead and three others injured, according to Harris County Sheriff Ed Gonzalez.
