Police officer arrested amid 'social media misuse' probe
A police officer has been arrested during an investigation into the alleged misuse of social media in Northern Ireland.
He is being questioned as part of a probe by the Police Ombudsman's Office.
A statement from the watchdog said: " Investigators from the Police Ombudsman's Office have this morning arrested a police officer.
"He is being questioned as part of an investigation into the alleged misuse of social media by a serving police officer.
"It was initiated after a decision by the Police Ombudsman, Dr Michael Maguire, to 'call himself in' to investigate information he has been made aware of."
Dr Maguire investigates complaints about the conduct of police in Northern Ireland but also has the ability to launch his own inquiries.
This arrest is not part of a wider Police Ombudsman investigation into the alleged misuse of social media by police officers and support staff.
The PSNI recently said it was carrying out inquiries into Twitter activity connected to people purporting to be police officers.
