Police in Argentina investigating the death of Liam Payne have raided the homes of two hotel employees and a “friend” of the former One Direction singer. The raids were carried out Tuesday night, while lockers of the workers at the hotel where the singer died were also searched, law enforcement sources in Buenos Aires told TMZ. Police believe the employees had been in contact with Liam before he fell to his death from a third-floor balcony at the CasaSur Palermo Hotel last month. According to TMZ's report, Liam's “friend” was identified by police by looking at messages on his phone to see who sold him drugs. However, it’s understood the person officers were looking to speak to was not at home during the raid last night. This development comes after police raided the same hotel late last month and seized electronic and paper records.
