Police in Philadelphia are scouring the area for five men caught on video at a local Geno's Steaks assaulting two couples then fleeing in their pickup truck and SUV – but not before a witness allegedly heard them scream their allegiance to ISIS.

The assault, captured on a surveillance video that was described by police as "too graphic" to release to the public, occurred June 11. But investigators are still seeking the whereabouts of the suspects, along with the identity and location of a woman described by witnesses as a getaway driver, Philly.com reported.

One of the victims, Patrick Kane, described the assault as horrific.

He told Philly.com he and his wife, Brooke Kane, had just left a wedding and after-hours nightclub with another couple and stopped at Geno's for something to eat. While finishing their meal, his wife's friend turned to a nearby group of people and asked for a cigarette, he said.

"That is when the guys just lost their minds," said Kane, to the news outlet.

Kane said one of the men in the group stood and shoved his hand over the woman's face and pushed her to the sidewalk.

"Don't mess with us," Kane said the man shouted, Philly.com reported. "We belong to ISIS."

Kane's wife then tried to help her friend to her feet, while telling the suspect the ISIS comment was not funny, Philly.com reported. She was then allegedly hit by one of the suspects.

Kane said he and the other man he was with then intervened, and a fight broke out.

"What went from putting hands on two girls became five guys attacking us," he said, to the news outlet.

Kane said he was punched in the nose, head and eye, and that the five men fled in the two vehicles. Witnesses at one point called police and emergency vehicles arrived on the scene and provided medical care to the couples.

"It is ridiculous that this even happened," Kane said, Philly.com reported. "I don't know why things have to escalate like this."

The two vehicles, described as a dark colored pickup truck and an SUV, had New Jersey license plates.
