Swaraj Abhiyan leader Yogendra Yadav's midnight arrest shows the "dictatorial tendency" of Delhi Police, Supreme Court lawyer Prashant Bhushan said on Tuesday.He also accused the Delhi Police of working at the behest of the Narendra Modi government, and vowed to challenge Yadav's arrest in court.Accoring to him, Yadav and some 100-150 people were sitting peacefully on Monday night at Jantar Mantar in the heart of the capital when the police asked them to end their protest."Yogendra Yadav told them (police) that the protest was peaceful. But they did not listen and dismantled the stage and detained the protesters."This shows the dictatorial tendency of Delhi Police. It also shows that they are (taking orders from) top political bosses," he added.Yadav and fellow activists were demanding adequate compensation for farmers affected by the proposed land bill as well as those hit by crop loss.
