Maybe this will disappoint u:
PENAL CODE (Chapter 224), Section 370
Buying or disposing of any person as a
slave.
Whoever imports, exports, removes, buys, sells or disposes of any
person as a slave, or accepts, receives or detains against his will
any person as a slave, shall be punished with imprisonment for a
term which may extend to 7 years, and shall also be liable to
fine.
