A firearms officer who shot a man thought a child was about to be stabbed, an inquest has heard.
Sergii Kuzmenko, a Ukrainian who "spoke limited English", was killed by Cumbria Police officers responding to reports of a man making threats to kill while a young child was present.
It happened at a house on Borland Avenue in Carlisle on 19 December 2022 and followed a 999 call from the man's sister.
The officer, identified in court as Officer C, told the inquest he "absolutely" thought Kuzmenko was going to stab the child.
At a previous hearing, the coroner ruled the two armed officers who shot Kuzmenko, along with two other armed colleagues, would be granted anonymity on the basis their safety could be at risk if their identities were revealed.
Giving evidence screened from the public and media, Officer C said he had been a firearms officer for seven years prior to the incident but had never fired a live round at a suspect before.
While at a police station that afternoon he had heard unarmed officers who were already at the scene calling for armed police, the inquest heard.
He said it was "the first and last time I've ever heard that kind of frantic message being passed".
When he arrived at the house he said there was "not enough time" to consider using his Taser instead of his firearm.
Counsel to the inquest Joseph Hart asked Officer C if he thought Kuzmenko was going to stab a child on his lap.
"Absolutely," replied Officer C.
He said it would have been an "unacceptable risk" to have to considered using a Taser instead of his firearm.
Hart asked the officer why he fired further shots after initially firing.
He said the child was - in his assessment - still at an "unacceptable risk" of being stabbed.
Earlier, the jury was read a statement from the force incident manager on the day of the shooting who had authorised the deployment of armed police.
The officer, identified in court as Officer K, was based in the force communications centre and stated that when information about the incident first came through on the force radio network they did not initially believe it "met the criteria for armed officers".
But unarmed officers who were initially sent to the property then said on the police radio network that Kuzmenko was holding a knife to a child's throat, the inquest heard.
Officer K then stated they heard the officers who were on the scene call for armed police.
In their statement to the inquest, Officer K described hearing "panic" in the voice of one of the officers on the scene.
Officer K authorised the deployment of armed police officers but stated over the police radio that they wanted to "get negotiators on the scene" and told the armed officers "please make sure you have less than lethal options".
Kuzmenko had been categorised as emotionally or mentally distressed (EMD) by the police.
The inquest in Workington, which is expected to last up to three weeks, continues.
