AUBURN — The early-bird shopping that began at 5 a.m. at Walmart seemed to go smoothly on Friday.

Shoppers who bumped into others in crowded aisles said, “I’m sorry” or “excuse me.”

But things didn’t go so well earlier in the morning.

Reports were heard of people fighting in the store around 1 a.m. Police who were sent to the scene were told that a brawl with at least 20 people was under way. Extra officers were routed to the scene and an ambulance was dispatched.

Early details of the fight may have been exaggerated.

“It was two teenagers,” said Auburn police Lt. Gary Boulet.

The scrap wasn’t even about hot sales and limited availability. According to Boulet, one kid bumped into another. Words were exchanged. One of the kids punched the other and gave him a fat lip. The teenager who was punched was gone when police arrived.

No arrest was made.

Beyond that, police said there were no additional problems reported at the store, in spite of a shopper turnout that inspired awe.

“They do have some big crowds over there,” Boulet said.
