"It's an insult that a prominent ulema and leader like Maulana Tauqeer Raza Khan was arrested and jailed," Yadav told reporters here.
Alleging that atrocities were being committed against Muslims and they were being insulted, the former chief minister questioned that for which crime Maulana Khan was arrested.
"People from every section of society felt bad on his arrest. The government's move backfired and failing to control the situation it was forced to release Maulana," he said.
Khan, leader of Ittehad-e-Millat Conference, was arrested on March 8 on charges of inciting communal feelings, attempt to murder and treason. The Sunni cleric was released on March 11.
The SP supremo also attacked the UPA government for not implementing recommendations of Rangnath Mishra Commission and Sachar Committee.
"If reports are not for implementation, what's the use of setting up a commission, which involves an expenditure of several crore rupees," he said.
Yadav also slammed the Congress-led government at the Centre for price rise. "Whenever Union ministers make any statement, prices go up," he said.
He alleged that the UPA government was working in the interests of industrialists.
