Police are asking for the public’s help identifying three men responsible for a brutal attack outside of a bar in North Park two days before Christmas.

The San Diego Police Department said the three men repeatedly and violently punched and kicked two other men and stole their wallet and iPhone outside of Seven Grand on University Avenue.

Police say two of the bar’s bouncers stepped in and stopped the attack, but the suspects stuck around and got into a confrontation with them. A witness recorded the exchange on their cell phone.

The suspects can be heard yelling and shouting at the bouncers. One of the bouncers has a bar stool in his hands and appears to use it as a shield when one of the suspects lunges at him.

An SDPD detective said the bar’s bouncers jumped in at the right time and may have saved the day.

Alex Shelton, a barber at Mr. Brown's Barber Shop two doors down on University, said he was proud of his friends at Seven Grand for stepping in.

“That's amazing,” he said. “It's good to know that there's people out there that stick their neck out to help other people.”

Shelton has been cutting hair at the shop for five years and said he’s never seen anything like what he saw in the video.

“Thank goodness those bouncers were there to help them out,” Shelton said.

San Diego County Crime Stoppers is offering a $1,000 reward for information that leads to the arrest of the three men. Police say the two men they attacked are OK but they're still healing from their numerous injuries.

An SDPD detective told NBC 7 they haven’t determined a motive in the attack. Witnesses told police the three suspects were drunk.
