Rome - One of two US teenagers arrested for the killing of an Italian policeman was blindfolded and handcuffed while in police custody, according to a picture that has sparked controversy.
Gabriel Christian Natale-Hjorth, 18, was arrested with Finnegan Lee Elder, 19, following the fatal stabbing overnight into Friday of Carabinieri policeman Mario Cerciello Rega.
In the picture, which has been circulated widely on Italian and international media, Natale Horth is shown sitting inside a police station, head bowed, with a band covering his eyes.
The way the suspect was treated "is completely unjustified and will not be in any way tolerated," Carabinieri Rome Commander Francesco Gargaro told RAI public radio on Monday.
A criminal investigation is ongoing to determine who blindfolded Natale-Hjorth, who took the picture and who leaked it to the media, Gargaro confirmed.
