The world's most expensive footballer did not report to training last week as expected, leading PSG to release a strongly worded statement criticising him.
Neymar's official website published photographs on social media of him back at work, yet the 27 year-old continues to be engrossed in controversy.
He had recorded an interview with Brazilian television network Band in which he was expected to talk about his future at PSG, with a return to Barcelona rumoured.
However, Band said the car where the recording of the interview was being stored had been stolen.
A statement from Sao Paulo civil police office confirmed a vehicle belonging to the journalist who interviewed Neymar had gone missing.
