Police are appealing for information after the aggravated robbery of a liquor store in Christchurch.

It happened last Sunday evening at the Sockburn Bottle-O on Main South Road.

A man wearing a black Oakland Raiders hoodie and black pants threatened the store manager with a knife and left on foot with a pile of cash and cigarettes.

Anyone who knows more is asked to call Police on 105.

Last week, it was reported Police were investigating a different liquor store robbery on the same night.

A spokesman told Stuff that they had received reports of four offenders, believed to be teenagers, stealing alcohol and money from an Edgeware store. 

Last month, Police arrested four people over an armed robbery of a Ferry Road store.
