A swastika has been daubed in a secure area of a police station in London, the Guardian has found.
The hate crime was not made public when the vile graffiti was found and the culprit has yet to be uncovered.
The swastika was found in February 2019 on an inside wall at Edmonton Police station in Enfield, north London, in an area accessible only to officers and staff.
The police station is close to a Jewish cemetery.
The Independent Office for Police Conduct said it had not been informed of the incident.
The Metropolitan Police said it had begun a thorough investigation into the graffiti, which it classed as a faith-based hate crime, but had not been able to identify the perpetrator.

The Metropolitan Police said graffiti was found on a wall in the lift lobby area of Edmonton police station on February 15.
"A thorough investigation was undertaken but no forensic opportunities were identified.
"As a result, it was not possible to identify who had drawn the graffiti. We take all hate crime seriously and have a zero tolerance approach."
The force confirmed that the area the graffiti was found in was "within the police station so not accessible to the general public."
