In this letter, we discuss a new method to probe the redshift evolution ofthe gas depletion factor, i.e. the ratio by which the gas mass fraction ofgalaxy clusters is depleted with respect to the universal mean of baryonfraction. The dataset we use for this purpose consists of 40 gas mass fractionmeasurements measured at $r_{2500}$ using Chandra X-ray observations, stronggravitational lensing sub-samples obtained from SLOAN Lens ACS + BOSSEmission-line Lens Survey (BELLS) + Strong Legacy Survey SL2S + SLACS. For ouranalysis, the validity of cosmic distance duality relation is assumed. We finda mildly decreasing trend for the gas depletion factor as a function ofredshift at about 2.7$\sigma$. This is the first result in literature whichdoes not find a constant gas depletion factor as a function of redshift usinggas mass fraction measurements at $r_{2500}$.
