If you get arrested while on an existing bail bond, the new arrest is considered separate from the first and if the new arrest requires bail, you would have to get a second bail bond.  Your old bond still exists and you still have to show up for court in order to get a refund if you paid it yourself.  If you paid a bail bond agency, it is non-refundable and if you made payment arrangements with the bond company, then you still have to complete those payments as per your bail bonds agreement.
