A PC's second set of blows to ex-footballer Dalian Atkinson on the night he was killed by her colleague was "wholly unjustified" and "outrageous", a disciplinary panel has heard.
Mary Ellen Bettley-Smith beat Mr Atkinson multiple times with her baton as he lay on the ground in 2016.
A criminal retrial last year acquitted her of actual bodily harm.
In a separate police hearing, she denies excessive force amounting to gross misconduct.
Mr Atkinson died after being tasered and kicked in the head by PC Bettley-Smith's West Mercia Police colleague, and romantic partner, PC Benjamin Monk, who was jailed for Mr Atkinson's manslaughter in 2021.
