CONCORD -- Two men who police said were drinking heavily at a Concord restaurant after the Super Bowl were arrested early Monday on alcohol-related charges after witnesses said one of the men pulled a gun and waved it around.

Police did not identify the men who caused the disturbance at the El Rancho Restaurant at 1450 Monument Blvd. because the investigation is ongoing.

Two heavily intoxicated men were in the bar area of the restaurant at 1:52 a.m., when patrons called police to say one man took out a gun and began waving it wildly, said Concord police Lt. Robin Heinemann.

They left the bar in a white Hummer and made their way onto northbound Interstate 680, where police pulled them over and arrested them at gunpoint, forcing closure of a small stretch of freeway at the Highway 242 junction, Heinemann said.

The driver was arrested on suspicion of driving under the influence and brandishing a weapon, Heinemann said. The passenger in the vehicle was arrested on suspicion of public intoxication, Heinemann said.

Several patrons reported the man had a gun, but officers never found a weapon, Heinemann said.
