The PSNI are investigating allegations of inappropriate conduct made against a male officer at its training college in east Belfast.
He has been re-positioned pending the outcome of the misconduct investigation.
The PSNI Professional Standards Department have also received a separate complaint of inappropriate language used by a female officer at the Garnerville police college.
Head of PSNI College Chief Superintendent Philip Knox said: “The Police Service of Northern Ireland expects its officers and staff to behave professionally, ethically and with the utmost integrity at all times.
"We expect all of our staff at the College to role model behaviours that re-enforce our organisational ethos and values. These values and standards are instilled into the learning of our student officers as they commence their journey in policing.
"All of our staff, including our newest employees, are supported and empowered to raise concerns if the behaviour of their colleagues, including those in authority, falls below the high standards that we all expect.
"On any occasion where concerns are raised with staff, we act immediately, with respect to due process, to investigate and robustly address those concerns.”
