The 23-year-old Mercury Music Prize winner was released on bail after reporting to police last week.
The alleged incident took place at a restaurant in Wardour Street, Soho, on 17 September.
Ms Dynamite, real name Niomi McLean-Daley, must again report to police in November. She has had three Top 40 hits in the UK including It Takes More.
