Several fake online applications for residence certificates have been filed under fictitious names like 'Shri Ram', 'Srimati Mata Sita' and 'Kawwa Singh' in Bihar's Khagaria, triggering a probe, officials said. 'Shri Ram' indicated his father's name as 'Dashrath', mother's name as 'Kaushalya' and his village's name as 'Ayodhya'. A certificate was earlier issued to 'Dog Babu' in Patna.
