This paper addresses the question of non-arbitrage (precisely No-Unbounded-Profit-with-Bounded-Risk, NUPBR hereafter) after a specific random time. This study completes the one of Aksamit et al. \cite{aksamit/choulli/deng/jeanblanc}, devoted to the study before the random time, by elaborating results for the part after the random time under consideration. We restrict our attention to honest times, and we characterize the pairs of market and honest time for which the resulting model preserves the NUPBR property. Furthermore, we characterize the honest times that preserve the NUPBR property. These findings are essentially based on new stochastic results that are interesting in themselves. Furthermore, we construct explicitly local martingale deflators for a large class of processes.
