A man allegedly brandished a handgun at a fellow bar patron in the midst of a heated argument at One Hundred To One Cocktail Lounge early Thursday morning.
Officers arrived at the bar shortly after 1 a.m. and arrested the man without incident, Arcadia police Sgt Kollin Cieadlo said. One Hundred To One is at 100 West Huntington Drive.
Police said they don't know what the two men argued about, but alcohol did not appear to be a factor in the dispute.
Arrest information was not readily available.
