• Government employment

Dear sir when i joined the excise department as inspector, i was asked to fill up an attestation form in which some questions were asked like 
1 have you ever been arrested
2 have you ever been detained, bound down
and so on
at that time , i was implicated in a criminal case u/s 354,366, 
but i didnt mention this in the form and wrote N/A instead
Now i have been acquitted in this case, now i know that if department come to know about my case, i will be terminated on grounds of concealment of facts and i will not be able to do govt service again in life.
i am again selected as inspector in income tax department through a fresh recruitment this year.
now again i will have to fill up the same form,
if i resign from the excise department(non-technical resignation) and mention the case details in the attestation form, can the income tax department check my documents submitted to excise department and deny me joining on the grounds that i have concealed facts in the previous depatrment.
