Police from New England Local Area Command are appealing for public assistance following the armed robbery of a post office in Armidale today.

About 4.15pm (Monday 7 September 2015) two men armed with machetes entered the store on Queen Elizabeth Drive.

The men threatened the two female staff members and seven customers who were inside the store at the time, demanding cash from the till.

One of the armed men jumped the counter and emptied both tills before demanding access to the store safe.

Money was taken from the safe and as the two men were leaving the store they assaulted a female customer and stole her purse.

The 80-year-old woman suffered minor injuries that did not require treatment.

A crime scene was established while detectives from Armidale conduct further inquiries.

The men have only been described as Aboriginal/Torres Strait Islander in appearance and had their faces covered with bandannas.
