Met put undercover police officer on restricted duties
An undercover police officer has been placed on restricted duties.
Det Con Jim Boyling, who worked in specialist operations at the Metropolitan Police, was investigated by the Met's Directorate of Professional Standards.
It followed allegations that he married an activist whom he was supposed to be spying on.
A Met spokesman said it would be thoroughly investigated, but the police were not able to comment further.
Scotland Yard said it acted "following allegations reported in a national newspaper on Thursday 20 January".
On Thursday, the Guardian reported that the undercover officer married an activist he was supposed to be spying on.
His ex-wife told the paper he encouraged her to change her name by deed poll in an unsuccessful attempt to conceal their relationship from senior officers.
She said she met the undercover officer in 1999 when he was working to infiltrate the Reclaim the Streets environmental group under the alias Jim Sutton.
After he completed his undercover work the officer is said to have vanished for a year, before reappearing and admitting his real identity as a police officer.
The couple reportedly had two children before divorcing two years ago.
The Met's move comes after Policing Minister Nick Herbert told MPs something went "very wrong" in the case of Mark Kennedy, another undercover police officer.
He caused the trial of six men accused of conspiring to shut down Ratcliffe-on-Soar power station in Nottinghamshire to collapse after he said he would testify for the defence.
Mr Kennedy spent a reported seven years posing as activist Mark "Flash" Stone.
