The Delhi Police probing the graffiti incident targeting Chief Minister Arvind Kejriwal on Tuesday said a man has been captured in CCTV cameras scribbling the messages.
The police on Monday registered an FIR and started a probe after graffiti bearing the AAP national convenor's name was found scribbled inside metro trains and at stations.
"A young man is caught writing on the signboards and coaches in the CCTV footage. He is suspected to be the same man who had shared the photographs of the graffiti on his Instagram account," an officer said.
