Whanganui police are still looking for a man in connection with the attempted robbery of the Pylon Dairy in Aramoho on Sunday.
While there were no significant updates on the case on Monday, police said they were continuing to investigate and were looking into positive lines of inquiry.

He had a small weapon and demanded money from the shopkeeper.
After leaving without taking anything, the man was followed by a member of the public in a white van, Staples said.
