Police say a boy as young as 12 could be responsible for a series of sex attacks in South Auckland.
Five indecent assaults on women in Papakura have been reported since December. Similar incidents have been reported in Pukekohe.
Police describe the person responsible as aged between 12 and 16, and of thin build.
During three of the attacks he was on a bicycle.
Police say the assaults are brazen, and very distressing and frightening for the women.
