New Delhi, July 24 (ANI): National Students' Union of India (NSUI) workers on Thursday held a protest outside the Rail Bhawan against the Shiv Sena for allegedly forcing a Muslim man to break his fast. The protesters were, however, detained by the Delhi police. Shiv Sena MPs allegedly forced a Muslim catering supervisor to break his Ramzan fast at Maharashtra Sadan in New Delhi last week. The MPs were apparently angry over not being served good quality Maharashtrian food.
