Kejriwal, who is on his first visit to Punjab since becoming the Chief Minister in February met the families of the two youths - Gurjit Singh (26) of Sarawan village and Krishan Singh (43) of Behbal Khurd village - and assured the all possible help.
He later told reporters that Gurjit was killed in police firing when he went to serve langar (a communal meal) to about 300 peaceful protesters. "As per rules, police fire warning shots in air and then into the ground...It was completely wrong," he said.
"We condemn the incident of sacrilege. Punjab is burning and we appeal to the state government to arrest those behind the incident. I demand that a copy of the FIR be given to Gurjit's family so that they could be aware of its contents," the Delhi Chief Minister said.
He said the state was on the "boil" after alleged incidents of sacrilege and asked the SAD-BJP government to take immediate steps to restore peace.
In the wake of the incident, Punjab Deputy Chief Minister Sukhbir Singh Badal put Moga SSP Charanjit Sharma under suspension for "lapses" in the line of duty.
Under pressure from several quarters, Punjab Police on Wednesday registered a case under various sections of the IPC in connection with the matter. It is being probed by a team led by ADGP Crime cum Director of Bureau of Investigation, Punjab, I P S Sahota.
