A man has been arrested at Sylvia Park shopping mall after trying to allegedly steal thousands of dollars of jewellery and injuring a man who tried to stop him.
A 27-year-old man who stepped in was allegedly hit in the face with a hammer.
Detective Sergeant Nick Poland from the Auckland City Crime Squad says, had it not been for the injured man's intervention, it's possible the alleged offender would have left the scene with nearly $40,000 of jewellery.
"After he was hit, the injured man desisted and others took over the chase resulting in up to six people detaining the accused until Police arrived a few minutes later.
"The shop owner and staff are very thankful to all those who helped arrest the alleged offender at 9.30 this morning.
