Although Jasper Luna was the legal representative and general manager of New Era Film, he was essentially just a puppet. He was Dao Ge's man, so he was fully aware of Lucy Clayton's influence and knew that if he didn't follow her orders, it wouldn't just be as simple as his own death. Lucy Clayton was a lunatic, capable of anything.
Thus, he had no choice but to call the police, and the report he filed stated there had been a break-in at his home, illegal detention, and robbery.
Robbery isn't defined solely by the theft of money, a stolen contract also constitutes robbery, so while his report was somewhat exaggerated, the response speed of the Beijing police was indeed very fast.
