Joining a New PSU after Resigning previous PSU but without informing both New PSU and previous PSU a

Dear Sir,
I am in Probation period of 1 year in a psu ‘x’ and I have executed a non judicial bond with Psu ‘x’ to serve it for five years after probation. Now, after 8 months of joining Psu ‘x’ ,I have got an offer of appointment from a new Psu ‘y’. What I am intending to do is resigning the previous Psu ‘x’ before joining new Psu ‘y’. But neither i have informed about my previous employment to new Psu ‘y’
not about my new job to the Psu ‘x’.Can this action of mine lead to any legal action??
If Yes ,then what will be an appropriate solution as I am very keen to join new Psu ‘y’??? Also I have to join new PSU withing 15 days..
Please reply as soon as possiible
THank You!!
