A woman, believed to be aged in her 30s, was walking along Wahrenui Rd, between Te Ngae Rd and Reeves Rd, when police say she was grabbed from behind and pushed to the ground between 6.30pm and just before 7pm on Saturday.

Police say the woman blacked out briefly, before fighting her attacker and screaming, causing him to run off.

The offender is described as a male Maori aged in his mid to late teens. He is a skinny build with a long thin face and no facial hair. He is likely to have a scratch or injury to his face as a result of the victim fighting back.

Anyone with information is asked to contact Rotorua Police on 07 348 0099.

Information can also be provided anonymously to the organisation Crimestoppers on 0800 555111.
