A woman charged with attacking R&B singer Lester Chambers at a San Francisco Bay Area blues festival has surrendered to authorities.
Alameda County Sheriff's officials said 43-year-old Dinalynn Andrews-Potter of Barstow turned herself in Thursday, a month after she was charged with assault and elder abuse.
Chambers is a member of Chambers Brothers, best known for their 1968 hit "Time Has Come Today.''
He said he was performing the Curtis Mayfield song "People Get Ready,'' which he dedicated to Trayvon Martin at a Hayward blues festival when a woman jumped on stage and shoved him to the ground. The 73-year-old singer called the July 13 attack a hate crime.
Andrews-Potter told police she had a stress disorder and that a repetitive part of the song caused her to snap.
