A police officer has been found guilty of assaulting a man by using a Taser on him during an arrest at Derby Railway Station.
PC Andrew Spiby, 53, from British Transport Police (BTP) was convicted of common assault after a two-day trial at Birmingham Magistrates' Court.
The BTP said the officer was called to a disturbance on a station platform on 28 May last year with another officer, who used incapacitant spray on the man twice before he was Tasered.
The other officer - PC John Severns - was cleared of assault.
The Independent Office for Police Conduct (IOPC) investigated after the arrested man complained about the level of force used on him in front of his family.
Deputy Chief Constable Adrian Hanstock from the BTP, said the officers had been responding to a "challenging situation" and added that the use of a Taser can "often be a difficult judgement" .
PC Spiby, of Suffolk Avenue, Derby, will be sentenced in June.
