An investigation is underway into a teenager's allegation she was assaulted by police during a wild teenage party in Auckland.
Pictures of a bloodied Ella Ekatone, 15, have been posted on Facebook by friends who attended an 18th birthday party on Wellington St on Saturday.
The party got out-of-control with reports of people passed out in the streets and when police arrived they were pelted with dozens of bottles.
About 35 officers tried moved to disperse about 150 party-goers and were responding to a 111 call from the property where the party was being held.
Her friend Anna Gardiner said the Howick College student was leaving the property as directed by police when she was shoved to the ground multiple times.
