Police have arrested someone following the aggravated robbery of a Four Square supermarket.

About 9pm on Saturday, April 20, a man entered the store on Balmoral Drive, allegedly armed with a knife.

Police say the knife was "presented at two staff members" while the alleged offender demanded cash and cigarettes.

"Thankfully, the staff were not harmed," says Detective Sergeant Neale Saunders.

The accused appeared in Tokoroa District Court on Tuesday, charged with aggravated robbery.

He was remanded in custody and is due to reappear again in court today.

"Tokoroa Police would like to thank all those who provided details after a public appeal for information," says Detective Sergeant Saunders.
