Copperfield foils robbers

I’m not a David Copperfield fan but this is just cool. Apparently Copperfield and two assistants were robbed at gun point after a performance. His assistants handed off their stuff, but Copperfield used sligh of hands to show the robbers his pockets were empty, while in fact they had his cell phone, wallet and passport.
The robbers were later arrested.
