Deputy Chief Minister Manish Sisodia was attacked with ink outside the Lt Governor's Office by a man who claimed that he was upset over the AAP leader undertaking a tour of Finland at a time when the city was grappling with a health crisis.
When Sisodia was about to get into his car after talking to media persons, Brijesh Shukla threw ink at Sisodia which splattered across his arms and on a portion of his forehead.
Sisodia said the ink attack on him was reflection of the "dirty politics of Congress and BJP".
Shukla, a resident of north east Delhi's Karawal Nagar, has been detained by police.
He said he was angry with the Deputy Chief Minister for visting Finland at a time when the city was grappling with rising cases of chikungunya and dengue.
The AAP leader had returned to the national capital last night from Finland after he was asked by LG Najeeb Jung to return on Saturday. However, he came back according to his schedule on Sunday.
Reacting to the attack, Sisodia said, "Delhi government is committed to working on health and education. But Congress and BJP are working on ink. They have nothing to do with Delhiites. Their aim is to stop our initiatives. This is the dirty politics of BJP and Congress."
He also challenged the BJP-ruled civic bodies to clear the "filth across the city" and hit out at Congress for "ruining" the city's education and health sector during its term.
"This is merely a diversionary tactic adopted by them since we are focusing on development," he said.
