New Delhi:  Delhi Chief Minister Arvind Kejriwal on Saturday directly took on Prime Minister Narendra Modi, saying he has declared an "emergency like situation" in the national capital after the Delhi Police detained an AAP MLA.

"Modi declares emergency in Delhi. Arresting, raiding, terrorizing, filing false cases against all those whom Delhi elected," Kejriwal tweeted.

"Dinesh Mohaniya arrested from his press conference in front of all TV cameras. What message does Modi want to give to everyone," the Aam Aadmi Party (AAP) leader questioned in another tweet.

Mohaniya, AAP MLA from Sangam Viar in south Delhi was detained by the police on Saturday for questioning in an alleged case of attack on locals from his residence when he was addressing a press conference.

The Delhi Police has registered two separate cases against the MLA for voluntarily causing hurt, misbehaving and mishandling locals.

Tughlakabad resident Rakesh Kumar, 60, had filed a case against Mohaniya on Friday after he allegedly slapped him and pushed him to the ground in Tughlakabad area of south Delhi when he tried to raise the water scarcity problem.

A day before, a case was registered against Mohaniya for misbehaving and mishandling some local women who had gone to the MLA's office-cum-residence to complain about the irregular water supply in the area.
