Youth gang members who have threatened dairy staff with pistols and machetes in armed robberies are taking to social media to boast about their loot.
Videos have been posted across social media, some dating back to 2016 from one gang known as We Strait Aych (WSH).
The gang is understood to be responsible for robberies at a Christchurch Night 'n Day store over six months, Stuff reports.
The Ferry Rd store has been the target of a number of robberies.
In 2016 staff members were threatened with pistols, machetes and knives in an armed robbery.
Last year offenders made off with cash and cigarettes in an armed robbery from the dairy.
A Youtube video shows pictures of group members posing with loot.
Night 'n Day chief executive Tony Allison told Stuff he could not believe the offenders were boasting online about the incidents.
Canterbury police area prevention manager acting Inspector Paul Reeves said he was appalled with the group's online bragging.
"It is disgraceful, this type of offending causes real harm in the community.
"Boasting about this type of behaviour and these crimes online further victimises those involved."
The group is known to police and officers have spoken to a number of individuals in regards to criminal offending.
Police are working alongside government and non government agencies to prevent this type of youth offending.
