Two more teenagers have been arrested for their alleged involvement in the aggravated robbery of a liquor store in Manurewa on Sunday.
Counties Manukau police say they have located and arrested a 16-year-old male and an 18-year-old male, who have been jointly charged with a 19-year-old male for the Sharland Liquor Centre robbery and stabbing.
Police had already located the 19-year-old male.
The three teens have now been charged with aggravated robbery, aggravated injury and theft.
The liquor store owner, Sarabjit Singh, was stabbed during the incident and remains in Middlemore Hospital in a stable condition. Police say he is recovering well from his stab wound.
Acting Detective Inspector Fa'a Va'aelua said he hopes the arrests offer some degree of comfort to the victim.
"We take these matters very seriously and will act quickly to apprehend those responsible."
The group of men were wielding double-bladed knives and set upon Mr Singh when he and his wife, Maninderpreet Kaur, were closing up for the day shortly before 10pm.
"My husband was going outside and he was near the door and he saw these guys [with] knives," Mrs Kaur told the Herald.
"When he saw them, he started screaming. And when he started screaming, I started screaming."
One of the men stayed outside, while the other two stormed the store brandishing knives.
"Both sides of the knife were sharp.
"On a kitchen knife, one side is sharp and the other side is not. But these [knives], both sides were sharp," she said.
One of the men stabbed her husband in the back while another went around the store picking up bottles.
They demanded she give them money, but she froze in shock, Mrs Kaur said.
At one point, her husband was hit repeatedly with a bottle by one of the men. "My husband was shouting and screaming."
As the men made to get away, Mr Singh - now covered in blood - attempted to get up.
"When he was stabbed, he's asking me still: 'Are you alright?'
"He was very brave. When they stabbed him, he fell to the ground. But he tried to run after them."
Mrs Kaur said friends and family had rallied to support their family, which includes their three sons aged 10, 12 and 13.
She wanted to thank members of the public who came to her husband's aid and ultimately led to the group running off.
