Wellington: The IS-inspired radical responsible for a supermarket knife rampage in New Zealand was watched for five years and jailed for three before authorities exhausted all avenues to keep him detained, Prime Minister Jacinda Ardern revealed on Saturday.
The 32-year-old Sri Lankan was only freed in July and had been under police surveillance since.
On Friday, he grabbed a knife off a supermarket shelf in Auckland and attacked seven people, leaving three critically wounded, before he was shot and killed by the armed police tasked with tailing him.
Court suppression orders meant Ardern could not explain why the terrorist had not been deported, but she said measures were already underway to strengthen New Zealand's terrorism suppression laws.
The man, who arrived in New Zealand on a student visa in 2011, came to the attention of police in 2016 after expressing sympathy on Facebook for terrorist attacks.
He was arrested in 2018 on charges of possessing a knife and objectionable material and was considered to be planning a "lone wolf" knife attack.
While in custody, he was further charged with assaulting guards, but attempts to have him charged under New Zealand's Terrorism Suppression Act were unsuccessful.
Although the man was found guilty on some charges, by then he had spent three years in prison on remand and "all avenues to continue his detention had been exhausted," Ardern said, although "risk mitigations were already underway".
Ardern added that changes to New Zealand's counter-terrorism legislation were expected to be approved by parliament before the end of the month.
"In late August, officials including the commissioner of police raised the possibility of expediting the amendments," she said.
Many details about Friday's attacker, including his name, were suppressed in an earlier court ruling.
Although this was lifted by a judge late Friday night, his family have been given at least 24 hours to appeal "the release of certain information", Ardern said.
"So while I can provide details concerning the individual's criminal history, there are issues relating to his immigration status, and actions taken by Immigration New Zealand in particular, which I cannot share just yet."
Police commissioner Andrew Coster said there had been nothing unusual about the man's actions in the lead up to the attack, and he had appeared to be doing normal grocery shopping.
Because he had a "high level of paranoia" around surveillance, Coster said the police kept their distance, and it took more than two minutes to reach the man and shoot him after he started his frenzied stabbing spree.
"We have had no legal grounds to detain this subject. Monitoring his actions has been entirely dependent on the surveillance teams being able to maintain their cover as they watched him over an extended period," Coster said.
Sri Lanka will cooperate with New Zealand's investigation into a knife rampage by an Islamic State-inspired assailant from the South Asian nation, authorities said Saturday.
Police shot dead the 32-year-old Sri Lankan after he attacked seven people in an Auckland supermarket on Friday. The man had been living in New Zealand since 2011.
"Sri Lanka condemns this senseless violence, and stands ready to cooperate with New Zealand authorities in any way necessary," foreign ministry spokesman Kohularangan Ratnasingam said in the Sri Lankan government's first comment on the incident.
Ratnasingam commended the quick response of New Zealand authorities in dealing with the attacker.
Sri Lankan police sources said criminal investigators had already interviewed the attacker's brother, who lives in Colombo, and were looking into all possible links. -- Agencies
