"Prashant Bhushan, myself and about 50 protesters have been detained from Delhi Gate. We were just standing with national flag and singing the national anthem.
"Police confirmed: no 144 in force, served us no order. Yet dragged and pushed into bus. Being taken to unknown destination," Yadav tweeted.
