This question deals with the extra-territorial jurisdiction of the Indian Penal Code (IPC).
The landmark case that established the principle described is Mobarik Ali Ahmed v.
The State of Bombay (1957).
In this case, the appellant, a Pakistani national in Karachi, made false representations to a person in Bombay via letters and telegrams, inducing him to part with money.
The appellant argued that he could not be tried by an Indian court as he was not physically present in India when the offense was committed.
The Supreme Court rejected this argument.
It held that the offense of cheating was completed in Bombay where the deception took effect and money was delivered.
The Court ruled that physical presence is not required; if the consequences of an act committed outside India are felt within India, the person can be tried under the IPC.
