A scuffle on Monday broke out between AAP supporters and policemen outside Rail Bhavan where Chief Minister Arvind Kejriwal was holding a dharna along with six ministers demanding action against policemen who refused to raid an alleged drug and prostitution racket last week.
The incident occurred when police disconnected Kejriwal's audio system prompting angry response from the AAP supporters. The police pushed some of the supporters when they tried to break barricades.
In the evening, a number of AAP leaders including Sanjay Singh and former journalist Ashutosh were seen having heated arguments with police for allegedly beating a number of their supporters including Model Town MLA Akhilesh Tripathi.
They also claimed that Transport Minister Saurabh Bhardwaj had been detained by police, which denied it.
In a tweet, Kejriwal said Tripathi was beaten up by the police "brutally". An AAP leader said Tripathi had to be admitted to a hospital.
Around 3,000 security personnel including from ITBP and Rapid Action Force were deployed around the protest venue.
Kejriwal and his ministers began the dharna demanding action against police officials who refused to carry out a raid on an alleged drug and prostitution racket in South Delhi last week.
Defying prohibitory orders clamped in the high-security area near the seat of power, Kejriwal and his cabinet colleagues had attempted to go to North Block housing the Home Ministry to lodge their protest but were stopped stopped near the Rail Bhavan by police.
Kejriwal said he has come prepared to stage dharna for at least 10 days and would continue the agitation further if need be.
