Aubameyang and his wife were handcuffed and tied up for a sustained period during the burglary, although club sources say neither suffered serious injuries.
The thieves broke into Aubameyang's home just outside of Barcelona in Castelldefels, where he lives with his wife and two children, in the early hours of Monday morning.
Aubameyang, 33, had just returned home from Barca's 4-0 win against Real Valladolid on Sunday, where he was an unused substitute.
Sources confirmed the gang forced him to open a safe that contained jewelry, among other expensive items, which they took.
The gang have not yet been caught, according to police sources.
