A caretaker of a mosque was arrested on Monday after he was caught carrying a live bullet to a public meeting at Delhi Chief Minister Arvind Kejriwal’s residence, the Hindustan Times reported on Tuesday.

Mohammad Imran, 39, was at the Janata Darbar with 12 Islamic clerics to seek an increase in the salaries of the Delhi Waqf Board staff. Imran – who is a resident of Loni in Ghaziabad and works at Masjid Bawli Wali in Karol Bagh – told the police that he had found the bullet in the donation box of the mosque. He kept it in his wallet and forgot about it, NDTV reported him as saying.

“The .32 bore live cartridge was recovered from his purse during the search and frisking by the security staff of CM’s residence,” Additional Deputy Commissioner of Police (North) Harendra Singh told the Hindustan Times. “He has claimed he found the bullet in a donation box two to three months ago and he intended to throw it in the Yamuna, but since he was yet to do it, he had kept it in his purse.”

The police have registered a case under the Arms Act.

This incident came a week after a man attacked Kejriwal with chilli powder at the state secretariat. The Aam Aadmi Party has blamed the police and the Bharatiya Janata Party for the incident.

On Monday, the party convened a special Assembly session to discuss the incident. Speaking in the Assembly, Kejriwal said “the string of attacks were planned by the BJP because they cannot see a common man like me as chief minister of Delhi”.

“If PM Narendra Modi cannot ensure security of an elected CM, he should resign,” Kejriwal said. “Or else, people will think that PM Modi has attacked Delhi’s residents and he is taking revenge from the people of Delhi.” The chief minister said he holds “no grudges against 95% of Delhi Police personnel”.

The Assembly later passed a resolution asking the Centre to amend the Constitution to put the Delhi Police under the control of the state government and make it accountable to the state legislature, the Hindustan Times reported.
