Two 19-year-old American tourists have confessed to killing an Italian policeman in central Rome early Friday, according to reports.

Carabinieri paramilitary officer Mario Cerciello Rega was stabbed eight times about 3 a.m. while investigating a reported robbery in Rome’s Prati neighborhood, according to Italian state media.

Rega was responding to the supposed meet-up spot where two alleged thieves, later identified as 19-year-old men from the US, were to return a bag and phone they had earlier swiped from a drug dealer, in hopes of collecting $112 from the dealer.

The two American tourists allegedly stole the property because the victim swindled them out of that sum in the nearby town of Trastevere — a popular tourist spot known for its nightlife.

Surveillance footage from the alleged robbery shows the Americans running away with the bag.

Following the theft, the victim called the police and told them he’d arranged a meeting with the robbers to retrieve his belongings.

Once Rega and another plainclothes officer arrived at that location, a fight broke out and Rega was fatally stabbed.

Italian authorities said the Americans were staying at an upscale hotel near the stabbing.

The Carabinieri police did not immediately confirm the alleged confession and haven’t released the suspects’ identities.
