Auckland police are hunting a man who allegedly punched a 72-year-old train manager while he was working and knocked him unconscious.
The incident happened about 4.30pm on March 28 on the Western Line between New Lynn and Fruitvale stations.
Detective Senior Sergeant Megan Goldie said the train manager had sat down to do some work. Next to him, a man and woman were having a verbal altercation, Goldie said.
“The woman has then gotten up and moved to sit across from the victim.
“Seconds later, completely unprovoked, the man has come over and punched the victim a number of times, rendering him unconscious.”
