One of the women who is suing the police after discovering that her former boyfriend was an undercover police officer has found a tracking device in her car, it has been reported.

The woman - known as Lily - had a two-year relationship with Mark Kennedy without knowing his real identity.

She is part of a group of women taking legal action against the police for the emotional trauma they suffered after forming intimate relationships with men who were later revealed to be spies.

Here and here she describes how Kennedy moved in with her and became involved in “pretty much every aspect of my life”.

This week, the German newspaper Die Tageszeitung reported that a tracking device - wrapped in tape - was found near a wheel of her car.

According to the story (in German here), it was discovered while she was at a conference - the Circumvention Tech Festival - that was held in Spain to discuss surveillance and censorship. Here is another story in the Catalan media.

At the moment, it is not possible to establish who has attached the device to her car. Lily has made a complaint to the Spanish police.

A group of activists has posted photographs of the device online here and asked anyone with information identifying it to get in touch. Here and here on Reddit are discussions about the possible origins of the device.
