The Herald was in court when the 25-year-old appeared briefly before a registrar during a typically busy morning list of cases.
His lawyer Richard Marchant entered a not-guilty plea on his client’s behalf.
Outside court, Marchant said the alleged assaults were also the subject of a police employment matter.
The 28-year-old and 39-year-old have also pleaded not guilty. All three men have been remanded on bail ahead of their next appearance on September 6.
