The Sydney man Benjamin Cohen, who was wrongly named on air by Seven News as the Bondi Junction killer, has hired a lawyer and is seeking damages from the network.

The university student has engaged defamation lawyers and issued a concerns notice to Seven, his solicitor Patrick George of the law firm Giles/George has confirmed.

Early on Sunday morning Seven’s breakfast show Weekend Sunrise and its YouTube channel named Cohen as the perpetrator without confirmation from the police.

During a live cross from Bondi Junction to the studio, the Sunrise co-host Matt Shirvington said the killer was “40-year-old Benjamin Cohen, dressed in a Kangaroos ARL jersey”.

Another reporter repeated the claim a few minutes later.

“The attacker, 40-year-old Benjamin Cohen, is known to police, his motives are not yet known, he was working on his own,” another reporter said. On YouTube a caption referred to Cohen as the attacker.

Several hours later New South Wales police named the man, now deceased, as Joel Cauchi, a 40-year-old from Queensland.

Seven has not revealed where its newsroom got the name from.

A Seven spokesperson said the network “sincerely apologises” for the error: “It was escalated immediately and rectified,” the spokesperson said.

On Saturday night Cohen’s LinkedIn profile was shared on X by accounts falsely claiming he resembled the attacker.

“It’s extremely disappointing to see thousands of people mindlessly propagating misinformation without even the slightest thought put to factchecking or real life consequences,” he said in a statement to Guardian Australia on the weekend.
