A remarkably large group of monkeys have always been known to cause havoc at government offices in both North Block and South Block. The aggressive animals swing effortlessly between the offices of the defence, finance and external affairs ministries and have even been spotted in the Prime Minister’s Office.

But now they have extended their reach and are moving effortlessly around Shastri Bhavan, a stone’s throw from there. Professional monkey catchers have been employed as the larger and more dominant black-faced langur strolls down the aisles of the crowded government offices.
