The body of a man believed to be a missing journalist was found dead Wednesday in a pension in the Floresta neighbourhood of Buenos Aires.
Police have not yet confirmed the identity of the man, though early media reports suggest it could be 27-year-old Martín Licata.
The man's dead body was found tied to a bed. He had a rubber device with a wooden handle tied around his neck, which investigators believe could have worked as a turnstile to strangle him.
Pension staff reported that the man had entered the facility at around 11.30am with an unidentified woman. She left the building at 1.30pm and remains at large.
Cleaning staff found the dead body in the afternoon, a police spokesperson told state-run news agency Télam.
Licata's family reported him missing on Tuesday after not having heard from him since Saturday.
A journalist and philosophy student, the 27-year-old had recently received threats and attacks on social media. He was a contributor to several left-wing and independent media outlets.
"It's strange that Martín has left without notifying anyone. He's an adult but he always sent me messages to make sure I was at ease about what time he was coming home", his mother Mónica Ibáñez told reporters.
Licata had allegedly also been beaten by police two months ago in the street.
Leftist groups had called for a march to demand answers about the young man's disappearance but it has now been cancelled.
