New Zealand had tried for years to deport the knife-wielding militant who wounded seven people at a mall in Auckland last week, the government said after it released more details on the attacker following the lifting of a court suppression order.

Court documents made public on Sunday identified the attacker as Ahamed Aathil Mohamed Samsudeen, 32, an ethnic Tamil Muslim from Sri Lanka. He had arrived in New Zealand 10 years ago on a student visa seeking refugee status, which was granted in 2013, the Reuters reported.

Police in Sri Lanka were making background checks on Samsudeen and talking to his family and friends for more information, said spokesperson Nalin Thalduwa.

"As far as I am aware the New Zealand government has not made a formal request for Sri Lanka to commence an investigation so we are simply gathering information at the moment," Thalduwa said.

New Zealand police were following Samsudeen and shot him dead about a minute after he launched his attack on Friday after picking up a knife from a supermarket display. He had been convicted and imprisoned for about three years before being released in July.
Samsudeen's family issued a statement to the New Zealand media describing their shock at the "terrible event".
After his arrest Samsudeen "used to call me once every three months or so. We felt his change and everyone used to scold him, especially his two bothers," his mother, who lives in the Muslim-majority town of Kattankudy on Sri Lanka's eastern coast, told a local news channel.

Samsudeen was inspired by the Islamic State militant group and was being monitored constantly but he could not be kept in prison by law any longer, the New Zealand government has said.

He came to the attention of the police and security services in 2016 after he expressed sympathy on Facebook for militant attacks, violent war-related videos and comments advocating violent extremism.

The authorities say they later discovered his refugee status was fraudulently obtained, so the government sought to cancel his visa and issued deportation notices.
