Tauranga Police have arrested a 27-year-old man in relation to an armed robbery at Bethlehem's Liquorland store earlier this month.

In a statement released this afternoon, Detective Sergeant Craig Rawlinson confirmed the arrest, which relates to an incident on August 19.

The man will appear at Tauranga District Court tomorrow, charged with aggravated robbery.

"At about 8:25pm, a male presented a pistol at a Bethlehem Liquorland shop attendant while robbing him of cash and several 'shots' of alcohol," explains Craig.

"The male then ran through an adjacent construction site and decamped in a waiting white van into Carmichael Road towards Brookfield."

The statement goes on to confirm that police are still investigating the matter and consider it likely that another person was also involved.

Police want to speak to any witnesses who may have seen these events on Wednesday 19 August 2015, or anyone who may know who else was also responsible.
