Delhi Chief Minister Arvind Kejriwal on Sunday blamed Prime Minister Narendra Modi for the arrest of AAP MLA Surender Singh.

Taking to micro blogging site, Kejriwal tweeted, "Modi govt gets Commando Surinder arrested. In less than 24 hrs, he gets bail. What is Modiji trying to achieve?"

AAP MLA Surender Singh, arrested for allegedly assaulting an NDMC worker, was on Saturday granted bail by a local court, with the legislator alleging that the case was motivated by political vendetta to "stifle and embarrass the ruling party of Delhi".

The court turned down police's plea for judicial custody of the accused and granted them bail observing that none of the offences for which they have been booked were punishable with jail term for more than seven years and there was no chance of their absconding or fleeing from justice.

"Further, the statements of the witnesses under section 164 CrPC have already been recorded. Also, the accused are not required for the purpose of custodial interrogation or for the purpose of effecting any recovery.

"Furthermore, it has been averred that this case is actuated by political vendetta. Thus, no prejudice is likely to be caused to the prosecution in case the accused persons are admitted to bail," the court said.

During the hearing, special public prosecutor Anupam S Sharma said that the accused were trying to fabricate evidence and threats have also been extended to victim Mukesh.

Senior advocate Ramesh Gupta, appearing for Surender, said, "There is a cold war between AAP and the party which is in power (in Centre).

He (Surender) is the member of the party which is in power in Delhi while the other party is in control of Delhi Police." He said the case was motivated by a political vendetta only to "stifle and embarrass the ruling party of Delhi".

Gupta also said fair investigation was not conducted in the case and if the accused have passed any alleged derogatory or casteist remarks, it was a matter of trial.
