It was "atrocious" to behave in "an inhuman" manner against the MPs who tried to stage a peaceful protest (outside the Prime Minister's residence), he said.
Just before the police thwarted their plans to meet Modi, they were visited by Delhi Chief Minister Arvind Kejriwal who offered his party's support for their cause.
The TDP had staged a similar protest at the chambers of Lok Sabha Speaker Sumitra Mahajan on Friday after they failed to get an appointment with her.
"They (Delhi police) behaved in an inhuman fashion, without even caring about the MPs' age".
The decision to protest was taken after party MPs held a meeting at Rajya Sabha member YS Chowdary's residence on Sunday morning to decide the future course of action.
New video shows Conor McGregor brawl at Barclays Center
McGregor hasn't fought for UFC since November 2016 and was stripped this week of the 155-pound championship he had never defended. Three matches scheduled for Saturday's UFC 223 card were scrapped because of the incident, cutting the card to 10 bouts.
He said he was supporting their demand for Special Status for their state. They had to be forcefully removed later in the evening.
The hours-long drama ended at night only after the TDP MPs were marshalled out from the House.
On March 16, the Telugu Desam Party (TDP) had quit National Democratic Alliance (NDA), led by the Bharatiya Janata Party (BJP), with party chief N Chandrababu Naidu slamming the Modi government over its refusal to grant special category status to Andhra Pradesh.
TDP's parliamentary leader Y S Chowdhary said, "We are fighting for Andhra Pradesh's five crore people". The TDP had also issued no-confidence motion notices against the government.
In the last one week, dramatic scenes were witnessed in Parliament with sessions getting adjourned over disruptions from the Opposition, including TDP legislators.
