Chambers had just dedicated the song People Get Ready to the late-Trayvon Martin, saying that writer Curtis Mayfield would have changed "there's a train a comin'" to "there's a change a comin'". Suddenly, a caucasion woman, identified as Dinalynn Andrews Potter, jumped from the crowd, reportedly yelling "It's all your fault", and attacked Chambers.
Dylan, Chamber's son, wrote on Facebook:
Dylan Here.... Lester was just assaulted on stage at The Russell City Hayward Blues Festival by a crazed woman after dad dedicated People Get Ready to Trayvon Martin. He is on the way to the hospital nowHe later posted that "Dad is OK" and a picture showing a large bruise on his side, saying "dad from today...bruised ribs muscle damage."
There has been an outpouring of comments on the Facebook page since the incident. It was mentioned, at one point, that Chambers is feeling that he may not want to do public performances again, showing just how deep such an unprovoked attack can damage a person beyond just the physical.
Andrews Potter was arrested on suspicion of battery, booked and released although additional charges may soon be added. A Facebook page is already up asking that she be charged with a hate crime.
