We propose a relativistic model for strange quark stars within the framework of MIT Bag model. In our model, we assume that the highly compact strange stars are anisotropic in nature which is an expected feature in the ultra high density regime. We discuss various physical features of the model and show that the model satisfies all the regularity conditions. By estimating the value of the Bag constant for strange star candidates like 4U 1820-30, Her X-1 and SAX J 1808.4-3658, we show that a wire range of values of the Bag constant are possible for such stars though, in the case of 4U 1820-30, the estimated value of the Bag constant has been found to be very close to its currently acceptable range. Nevertheless, our results are in agreement with the recent CERN-SPS and RHIC data.
