A police sergeant has denied groping a female colleague by grabbing her bottom during a training exercise.
Jason Scott Renwick, 49, is charged with one count of sexual assault over the alleged incident at a Brisbane training facility on February 6, 2019.
He pleaded not guilty at the start of a trial in the Brisbane District Court on Monday.
The training exercise on a staircase involved officers passing another officer in a cover position and tapping or squeezing them on the shoulder or thigh, crown prosecutor Brendan White told the jury in his opening address.
The final officer was also required to say "last man".
Mr White alleged Renwick "put his cupped hand on the underside of her right buttocks and squeezed it" before saying "last man".
"He then continued to walk past her while laughing and said, 'Don't hit me'," Mr White said.
The woman allegedly responded, "What the f*** was that?".
Renwick allegedly spoke to the woman later that day asking, "Did I overstep a line?"
She replied saying she was OK "but it isn't OK".
The woman and two officers who witnessed the alleged incident, are expected to give evidence before a jury.
The trial is set down for four days before Judge Katherine McGinness.
