Police are looking for at least two men in connection with the aggravated assault of a security guard at a Northeast Austin nightclub last weekend.

Detectives say five men assaulted Marc Chappelle, an armed security guard at Club el Navegante, 1611 Dungan Lane, early Saturday morning after he denied entry to two of the men and demanded that another refrain from urinating in the club’s parking lot.

At some point in the evening, two of the men left the club for a time and returned shortly thereafter. Chappelle told them they were too intoxicated to re-enter the bar, leading to an argument, said Austin Police Department Detective James Mason.

Meanwhile, another man began urinating the parking lot. When Chappelle demanded he stop, a struggle began, causing Chappelle to use his pepper spray.

The other men raced toward Chappelle carrying bricks, Mason said. Fearing for his life, Chappelle fired three rounds, one of which hit one of the men.

The four unharmed men took off in a green four-door Honda. Police identified two of the suspects — Jose Benjamin Cabrera-Diosdado, 18, and Luis Enrique Ortega-Vazquez, 26 — who were arrested later and taken to Travis County Jail.

The fifth man was taken to the hospital where he was treated for injuries that were not life-threatening injuries, Mason said. It was not known whether the man has been released or whether a warrant for his arrest has been obtained.

Chappelle was unharmed in the attack and is suspended from work until the investigation is complete.

Police are asking anyone with information to call APD’s Northeast Division at 974-5491.
