In the meantime, Sharma bowed down to touch Kejriwal's feet, he suddenly attempted charging chief minister but it was swiftly foiled by security staff of Delhi Police", the joint Commissioner added. The CCTV footage shows that Sharma tried to touch Kejriwal's feet and tried to attack on his face but Chief Minister security staff caught hold on him.
