Than Singh, who hails from Rajasthan, is a head police constable whose current post is at Red Fort, Delhi. Apart from his job, he also teaches slum children. The place is known as Than Singh Ka Pathshala. The idea of teaching these slum children came to Than Singh’s mind when he saw poor children from nearby places doing work like rag picking etc. He knows how it feels to live in a slum, as he himself grew up in the jhuggi-jhopdi colony at Meera Bagh. When he started the pathshala, there were only four students with him. But already, he has more than 50 students, all of whom belong to slums, and whose parents don’t have enough money to send them to school.
