Mr Ciolac, a 35-year-old builder who was originally from Romania, smashed through the first layer of the station’s double glazed windows with the knife, appeared to “lick” the blade at officers through the door, and hit police cars before the two armed officers arrived, Derby Coroners Court had heard.
“However, for reasons that remain unclear, within 20 seconds of armed officers walking into the car park at Ascot Drive, Mr Ciolac rushed towards one of the officers armed with a knife, leaving him with no other option than to fire his weapon.
The court was told that the officer, whose identity is protected by an anonymity order and was referred to as Officer A, fired the gun between 18 and 22 seconds after he entered the car park with another armed officer, called Officer B.
The officer said he told Mr Ciolac to drop the knife, but did not say he was armed police, before he ran at him with the weapon raised.
“When an incident of this nature takes place, there is rightly a robust investigation undertaken by the Independent Office for Police Conduct which, after reviewing footage and the statements by all those at the scene, found that the force used by the officers, including the officer who discharged their firearm, was proportionate.
