A serving Strathclyde Police officer has been arrested in connection with "ongoing enquiries".
The arrest of the 47-year-old man at the weekend was confirmed by Strathclyde Police on Thursday. The force said that it was not in relation to an ongoing inquiry into allegations of phone hacking.
The arrest of the officer was first revealed by investigative journalist Charles Lavery on his blog.
He wrote that the arrest of the Strathclyde Police officer was in connection with Operation Rubicon, which is in relation to allegations of phone hacking, breach of data protection. It was set up in response to evidence presented during the Tommy Sheridan perjury trial.
However, on Thursday a Strathclyde Police spokeswoman said: "A 47-year-old police officer has been arrested in connection with ongoing enquiries. A report will be submitted to the procurator fiscal in due course.
"He was neither working on or arrested as part of Operation Rubicon."
Operation Rubicon was recently highlighted at the Leveson Inquiry into press standards where Strathclyde Police Chief Constable Stephen House spoke about it and also revealed in the past five years his force has held 45 inquiries into leaks to the press.
