The Delhi Congress staged a protest near Chief Minister Arvind Kejriwal's residence here on Monday accusing the Aam Aadmi Party of being responsible for Sidhu Moosewala's killing in Punjab a day before.

The protesters, including Delhi Congress president Anil Kumar, marched from Sushruta Trauma Centre towards Kejriwal's residence but were stopped by the Delhi Police at a barricade.

"The AAP government is responsible for the daylight murder of Sidhu Moosewala. Arvind Kejriwal should answer why Moosewala's security cover was withdrawn although his life was under threat and it was known to intelligence agencies in Punjab," Kumar said.

Youth Congress activists on Monday also held protests in Jammu against the Aam Adami Party and its government in Punjab and termed the killing of singer Sidhu Maoosewala as a political murder and questioned the decision to downgrade his security.

The protesters demanded the resignation of Punjab Chief Minister Bhagwant Mann for the alleged deterioration of the law and order situation in the state.

Hundreds of youth Congress workers, including Leh Youth Congress president Udhay Bhanu Chib, assembled at the Gandhinagar-situated head office of the AAP here and held massive protests, holding the Punjab government responsible for Moosewala's murder.

They also set afire Mann's effigy. The irate protesters also tore posters and hoardings of AAP chief Arvind Kejriwal at the party office.

"We demanded the resignation of Punjab Chief Minister Bhagwant Mann and the state DGP. They are fully responsible for his (Moosewala's) killing. It was a deliberate political murder," Chib told reporters here.

He said the law and order situation in Punjab has worsened after the AAP came to power in the state.

"Over 40 murders have taken place during its tenure. A famous artist was also killed brutally in the absence of the adequate security," Chib said.

"There was information to the government by various intelligence agencies that there was a threat to Moosewala's life," he claimed, adding despite that the Punjab CM downgraded his security.

AAP chief Harsh Dev Singh lodged a complaint with police over the tearing of posters at the party office by Congress workers.

The Punjabi singer and Congress leader was shot dead by unidentified attackers in Mansa district of Punjab on Sunday, a day after his security was curtailed by AAP government in the state.
