The man, identified as Kamaluddin, a resident of 24 Parganas district of West Bengal, was immediately nabbed by Bukhari's Personal Security Officers (PSOs) and later handed over to local police.
"The incident took place when the Imam was leading the namaz of 'Maghrib'. A man suddenly threw a plastic bottle which had kerosene at him from behind. The attacker was caught by Imam's PSOs. He has been taken to the nearby police station," said Amanullah, Bukhari's official spokesperson.
Additional Commissioner of Police (Central) Alok Kumar said that the man has been taken into custody and is being questioned as to why he did the act.
Some drops of kerosene fell on Bukhari's cloths and some on the floor, but nobody was hurt, police said.
