Stephen Bardo, a member of the 1989 Flyin' Illini Final Four team and current Big Ten Network analyst, was critical of the police officers who arrested Paul.
He called out the Champaign community and accused officers of racial profiling.
He tweeted: "I love my time there but the community of Champaign is stuck in the 60's. Racism is overt there. Needs to change."
The tweet was later deleted, but Bardo continued debating with people, some who agreed and others dissented. Read Marcus Jackson's story in the News Gazette for more comments from Bardo.
Darius' brother Brandon also spoke up, offering an extended statement he posted in two tweets.
"I understand my brother shouldn't have been out that late drinking. Let's not forget it's a college campus, what underage kid isn't out past curfew drinking? No excuses, there will be consequences for his actions. I also understand that law enforcement must do their jobs, but their jobs don't entail them to follow someone & then pursue them for no reason. Why did they feel the need to stop him in the first place? Reports say he "acted suspicious" & "appeared to be trying to avoid contact with police." Even if true, I don't know many kids (inebriated or not) that wouldn't try to avoid contact with the police? (Some) of these cops look for reasons to get into these types of situations and it's not right."
"4 amazing years at UI & I had a great relationship w/law enforcement. Met a lot of well respected police officers. Sometimes they were people that didn't necessarily like us athletes & I've spoken w/many cops that went out of their way to make sure we were ok & out of trouble. Unfortunately not everyone has our best interests at heart. Please don't put words in my mouth or assume, all I'm saying is from reports it didn't look like there was much reasoning for my brother to be stopped. He shouldn't have tried to evade them, but obviously wasn't thinking straight, hopefully we can move on & talk about more important things, like making it so chipotle delivers!"
Darius Paul was arrested early Tuesday morning for underage drinking and resisting a police officer.
The News Gazette first reported the story about Paul, who sat out last season after transferring from Western Michigan.
Paul was apprehended near his apartment and told police he'd been drinking. He was taken to jail in Urbana, where he later posted bond and was released.
