The official said the transfer was done on administrative grounds. The assailants -- Mohit alias Sunny (23) of Hamirpur, Lavlesh Tiwari (22) of Banda and Arun Maurya (18) of Kasganj -- were arrested soon after the dramatic shootout outside the Prayagraj hospital where policemen were escorting the brothers for a medical check-up Saturday night. 

 The trio were taken from Prayagraj at noon and reached Pratapgarh at 2.10 pm, officials said. One of the sons of Atiq Ahmad is currently lodged in the Prayagraj Central Jail in Uttar Pradesh. PTI
