Jakob Lindenthal, a German exchange student at the Indian Institute of Technology-Madras (IIT-M) in Chennai learnt it the hard way that foreigners in India do not get to exercise their freedom of speech.
He was famously photographed at protest rallies against the Citizenship (Amendment) Act (CAA) in Chennai invoking his German heritage to warn people of the consequences of marginalisation and disenfranchisement of minorities.
According to reports, Jakob was called in by the immigration department and asked to leave once he expressed his opposition to the CAA.
