Delhi Chief Minister Rekha Gupta was attacked by a man during a weekly public hearing at her residence on Tuesday, in what police described as a major security breach.

The attacker, identified as Rajesh Sakriya from Rajkot in Gujarat, was swiftly overpowered by Gupta’s security personnel and is being questioned, police officials said. Preliminary information suggests he was upset over a Supreme Court ruling to relocate stray dogs in Delhi NCR, according to his family.

Gupta, a senior leader of the ruling Bharatiya Janata Party (BJP), was examined by doctors after the incident. Party leaders condemned the attack, with Delhi minister Manjinder Singh Sirsa alleging a “political conspiracy” and calling for a full investigation.

“One person present at the meeting attacked the Chief Minister. We condemn the attack. It should be investigated if this attack was politically motivated,” said BJP leader Harish Khurana.

Opposition Aam Aadmi Party (AAP) also condemned the assault. “There is no place for violence in a democracy,” said Atishi, AAP’s leader in the Delhi Assembly. “We hope the Chief Minister is completely safe and that strict action is taken against the culprits.”

Eyewitnesses said the attacker approached Gupta with papers before suddenly lunging at her. Delhi Police Commissioner S.B.K. Singh will oversee the probe into how the man managed to get close to the Chief Minister.

The attack has raised fresh questions about the security arrangements for top political leaders in the capital.
