 Suspicion grew that, to gain revenge for this considerable slight, Omichand had secretly urged Siraj ud Daula to attack the British and that suspicion was confirmed when two letters from the nawab's camp (Siraj ud Daula's camp) were found addressed to Omichand.Kissendass, who was a house guest at the time of Omichand's plight, was also arrested when found with Omichand.They were then incarcerated in a small jail near Fort William's southeast bastion, in a room that was used to house drunken and disorderly sailors.
