RIALTO >> Walmart officials say they are comfortable with the security in place Thursday night, despite three fights at a store here Thursday night.

“The fight at the Rialto store was an unfortunate and isolated incident to an otherwise very safe event,” corporate spokeswoman Betsy Harden said. “Providing our customers with the best and safest shopping experience is always our top priority.”

Police officers descended on Walmart in Rialto after a brawl between two men injured a police officer who tried to break up the fight Thursday night.

The injured officer was transported to St. Bernardine Medical Center in San Bernardino with a broken wrist, police officials said. He was treated and released late Thursday night.

A Walmart manager said the doors were originally scheduled to open at 8 p.m. but with the more than 5,000 people in line they made the decision to open the doors early leaving nearly 1,500 people waiting in line to get in the store, which police said led to the melee.

“We were fine waiting and didn’t feel scared until the fight broke out,” said Marta Vargas of Rialto. “The police jumped in quickly and took care of the problem.”

Police said there were three fights total shortly after 7 p.m. at the store at 1610 S. Riverside Ave., two of which were inside over merchandise and the third outside that caused injury to the officer.

“We saw a man and a woman fighting inside over a flat screen TV,” said Jamal Jones, 56, of Rialto. “This is my first Black Friday and my last. The crowds are pushy and people are downright rude.”

Colton police along with the San Bernardino County Sheriff’s helicopter assisted Rialto officers with the incident.

All of the people involved in the fights were taken into custody, but one of the men involved in the fight outside was arrested for suspicion of assault with a deadly weapon. Police said he was allegedly kicking the other man in the head when he was down on the ground.

Walmart corporate officials said safety of customers and employees is the greatest importance.

Harden said Walmart coorporate had a wristband system, which they had in place. Harden said it afforded consumers guaranteed deals hile being able to shop the store for merchandise.

“We’re comfortable with the safety and security plans we put in place,” Harden said. “We don’t feel we have the need to raise our security and that the events from last night were isolated incidents.”
