Police say they have received no complaints of assault after singer Amy Winehouse appeared to punch a fan during her performance at Glastonbury. 
A spokesman at the festival said there would subsequently be no investigation. Founder Michael Eavis defended the star, saying she had appeared to lash out after being touched by a fan.
He added that Winehouse had asked if she could headline next year's music event, and he described her show on Saturday as a "triumph".
