Police have released CCTV footage of a man who they believe is opportunistically preying on young women on Auckland's North Shore.
On Friday afternoon a woman in her mid-20s was assaulted from behind and left with a dislocated shoulder while jogging on a track between Browns Bay Road and Beechwood Road.
Camera footage shows a man was in the area at the time of the attack.
The man is described as mid-20s, 5'10" and overweight - walking and then running from a walking path.
There were two other incidents where women were assaulted on a track between Murray's Bay and Rothesay Bay nearby in October.
RNZ reporter Jordan Bond asked Detective Senior Sergeant Callum McNeill if there was any sexual element to last friday's attack.
