SAN DIEGO- An apparent argument over a military uniform sparked an altercation that led to the stabbing of an Army servicemember in the Gaslamp Quarter Thursday night.

KGTV reports that according to San Diego police, the incident happened at about 11:40 p.m. in the 600 block of 5th Avenue.

Witnesses said a man was wearing what appeared to be a Class A Army uniform at a bar when he was approached by an active-duty Army serviceman and a military veteran who pointed out some errors on the uniform.

According to the two men, the uniform was missing a patch and the rank was upside down, leading them to question if it was a "stolen valor" situation.

New outlets report when the men pointed out the uniform issue, the uniformed man reportedly became angry, brandished a knife and threatened the two men. The confrontation became physical, and police said the active-duty serviceman was stabbed multiple times before others intervened.

A pedicab driver witnessed the incident and flagged down a police officer, who arrested the uniformed man.

Police have not confirmed the suspected attacker's identity or if he has served in the Army.

KGTV reported that the serviceman's injuries did not appear to be serious.
