Police are investigating the "vicious assault" of a woman outside the Sunnyvale train station in west Auckland.
A 26 year-old woman was attacked about 7.40pm last night on the walkway which leads toward Newham Place and Sunnyvale.
According to police, a male followed the female from the station having disembarked from the same train.
He then attacked the female from behind, grabbing her clothing and punching her in the face, in an attempt to get her onto the ground.
"The female resisted the assault by kicking and punching the male and finally scratching his face. In a gutsy display of courage the victim was able to repel what was clearly a premeditated and sinister attack," said Detective Sergeant Litherland.
The male ran back in the direction of the train station and the victim, who was left bruised and shaken, sought assistance from the police.
The male was described as a Pacific Islander or possibly Indian aged in his late 20's or early 30's with short black hair.
He had a skinny build and is likely to have scratch marks to his face. He was wearing a long sleeved grey sweat shirt and black full length pants and black shoes.
Police want to hear from anyone that may have seen this male either on the train or may know of his identity.
