Three Edinburgh-based police officers are under investigation after a video mocking Kati Price's disabled son was allegedly posted in a group chat.
One of the British Transport Police officers has been placed on restricted duties as the investigation is carried out, and may go on to face criminal charges.
The three officers are based at BTP's Torphichen Place station.
The Sunday Mail reports an officer was filmed making remarks about 17-year-old Harvey, Price's son, and two colleagues added comments after the video was posted in a chat group.
It's understood a mobile phone has been seized as part of the investigation and all three will face a disciplinary hearing later this year.
A whitstleblower alerted senior managers to the incident and racist language was allegedly found to have been used.
A force spokesman said: “We can confirm that a British Transport Police officer is under investigation in relation to allegations of gross misconduct and potential criminal offences.
“He is currently on restricted administrative duties.
“Two further officers are also under investigation following claims of misconduct. This inquiry is in its early stages and is being overseen by our professional standards department.”
A source told the Sunday Mail: “This was brought to the attention of senior officers by a colleague who claimed racist terminologies had been used.
“A mobile phone was seized and the three officers will be up at a disciplinary hearing later in the year.”
Harvey has autism, is partially sighted and has a condition called Prader-Willi syndrome which means he gains weight easily.
The officer accused of mocking Harvey has been transferred to a station in north-east England.
The other two constables are also facing misconduct charges but remain on normal duties.
A spokesman for anti-racism campaigners Hope not Hate said: “Abuse and intolerance of anyone for a disability or ethnicity is wrong.
“Those who serve to protect us from crime are rightly held to an even higher standard because of the trust we invest in them as public servants.
"Anything less is a derogation of that public trust, coming at a time when hate crimes have been rising."
