AAP leader Arvind Kejriwal today held a "silent prayer" at Assi ghat on the bank of Ganges here to pray for "wisdom and good sense" to those allegedly involved in last night's assault on Somnath Bharti. Kejriwal, accompanied by his party colleagues Manish Sisodia and Sanjay Singh, sat near Assi Ghat for over one-and-half hour.
