A teenager has been charged following an aggravated attempted armed robbery of a convenience store in Cardiff on the weekend.

Just after midnight on Sunday 26 April 2015, a male armed with a knife entered a convenience store on the corner of Gertrude and Helen Streets.

It will be alleged the male threatened a staff member, when the employee suffered a deep cut to his hand.

The armed male fled the scene empty handed. The staff member was treated at the scene by Ambulance Paramedics, before being taken to John Hunter Hospital.

Police were called and commenced investigating the incident.

Following inquiries, yesterday (Tuesday 28 April 2015), officers attached to the Lake Macquarie Special Operations Group attended a home on Mary Street, Cardiff, where a 16-year-old boy was arrested.

A number of items were seized from the home for forensic examination, including an electronic device and clothing.

The teenager was taken to Charlestown Police Station, where he was charged with aggravated robbery and an unrelated outstanding warrant.

He has been refused bail, to appear at court today (Wednesday 29 April 2015).
