Wiltshire Police Pc Lee Birch, 30, is said to have used the weapon against Daniel Dove after booking him in at a custody unit.
He is also accused of an allegation of misconduct in public office relating to his actions as he handcuffed Mr Dove and strip-searched him in the cell.
Swindon Crown Court heard the case was a private prosecution launched by Mr Dove and Birch had first appeared before magistrates last month when he answered a summons.
Robin Shellard, representing Mr Dove, said the Crown Prosecution Service was considering whether to take over the case.
Birch was told that because he was a serving Wiltshire officer, the case was being transferred away from the county and being sent to Bristol Crown Court.
Judge Douglas Field released Birch on bail and fixed a provisional plea and case management hearing for October.
