Police in Argentina have arrested the girlfriend of the sunwheel-inked assassin accused of trying to kill Argentine vice president Cristina Fernandez de Kirchner.

Agents from the Antiterrorist Investigation Unit Department arrested Brenda Uliarte, 23, on 4th September as she waited for a train at Palermo station, Buenos Aires, as part of the investigation into the alleged attempted killing.

Investigators believe Fernando Sabag Montiel, 35, may not have acted alone in his alleged plot to kill Fernandez de Kirchner outside her home in the Argentine capital on 1st September.

According to investigators, who studied CCTV footage, Uliarte made a good part of the journey to the scene of the alleged attempted murder with her partner.

Calls to and from Sabag Montiel’s mobile phone also contained relevant evidence, said reports, but no details regarding the content of said calls have so far been revealed to the public.

Cops also seized Uliarte’s phone as part of the investigation.

Uliarte reportedly took to social media on the day of her arrest to deny being involved in the alleged plot to kill Argentina’s vice president but closed her account shortly afterwards.

In a television interview on 2nd September, she had also denied having anything to do with the alleged crime and revealed she had met Sabag Montiel “at a party”.

According to reports, she sold pornographic images of herself online.

Police reportedly believe she lied during questioning, specifically about how long she had known Sabag Montiel for and when she had last seen him.

Police have not ruled out more arrests in connection with the alleged attempted killing.
