The gang is headed by a Romanian named Catal‹n, who is currently incarcerated in Salamanca. He reportedly gave instructions that his subordinates were not to sell the violin for less than $1 million euros, although it is worth up to 2.5 million euros, according to ABC.
It is unclear where the violin came from or when it was stolen; it reportedly doesn't match up with any Strads known to be missing.
The mafia gang operates in Spain, Romania, and various EU countries; it is known for forcing women into prostitution. Spanish media report that it is possible one of the gang members played the instrument.
