Damian Lillard is being accused of standing by while his entourage beat up two brothers in Portland's Old Town district on Saturday morning.

Jermaine Ulinwa said that he took a photo of Lillard with his cell phone after he spotted him walking toward a parking lot.

“So I took a picture. And so Damian Lillard was upset that I took his picture, so when he turned around he's like, "Did you just take my picture?" said Ulinwa.

“And his entourage just turned around too and they're like, ‘Did you just take a picture of Damian Lillard?’ ... and I said 'Yeah, I did.' And so I saw that he was clearly upset, they were upset and I was like, 'Can I apologize to him? I'll go up right now and apologize to him,'” the brother said.

Philip Ulinwa says he was punched and kicked repeatedly, enough to break his nose and require stitches in his lip.

"I'm getting hit from behind, I'm trying to fight the guy in front, trying to defend myself and there's guys trying to hold me down," said Ulinwa. 

Lillard was recently named the 2012-13 NBA Rookie of the Year.

“Damian Lillard basically instigated it, because he actually looked like he was going to go up to my brother and start fighting him. And since he did that, the rest of the guys started getting riled up too and like they thought it was okay to just start fighting out of nowhere,” said Phil Ulinwa.

Police confirmed they are investigating the incident.

“What we do know for certain at this point is Damian Lillard is not a suspect in this incident at all," said Portland Police spokesman Sgt. Pete Simpson. "Police did talk to him there. He remained at the scene. What we don’t know is if these people were actually associated with him or people standing in a group or hangers on. We're not really sure yet."
