Updated 11:30 a.m.: Revised to include information from an arrest-warrant affidavit.

Dallas police have arrested a man they say shot a valet at an Uptown Dallas nightclub over a parking dispute early Monday.

Nnaemeka Ewenike Onyedebelu, 28, went to the One Sette nightclub on McKinney Street with four companions around 12:30 a.m. but was refused entry "due to previous problems and disturbance these individuals would cause," according to an arrest-warrant affidavit.

When they demanded a refund for the $20 they'd paid to park, a valet gave them $10 back. One of Onyedebelu's companions began fighting with two valets, the affidavit says.

As they struggled, Onyedebelu came up behind one of the valets and hit him in the head with a handgun, then shot him once in the arm, the affidavit says.

The crowd dispersed, but Onyedebelu returned to speak to police around 1:20 a.m., according to the affidavit. The handgun was in his passenger seat.

The valet was taken to a hospital and was stable, authorities said.

Onyedebelu was arrested on a charge of aggravated assault with a deadly weapon. He posted $525,000 bond Monday.
