The Aam Aadmi Party (AAP) will be raising the issue of former party leader Yogendra Yadav's detention in the Parliament today.
The former AAP leader was detained by the Delhi Police during a farmers' protest at Jantar Mantar last night.
He was also prevented from speaking to the media today by policemen.
Yadav, who was trying to march towards the Prime Minister's official 7 Race Course Road residence, has alleged that he was "brutally assaulted".
