Police are hunting for a man who held up a Dunedin dairy at the weekend.
It was the second time in three months that Ashvin Patel, the owner of the Sai Food Market on Prince Albert Rd, has been robbed.
In the latest incident a man entered the shop at 9.36am on Saturday and brandished a large knife at Mr Patel.
Mr Patel scrambled to get to the safety of a room behind the shop and called police.
The robber slipped behind the counter, took several packets of tobacco, then ran from the store.
Mr Patel chased him but lost sight of him.
He said the incident had left him shaken, especially after almost exactly the same thing had happened in August.
He believed it may be the same person.
