We present infrared and radio observations of IRAS 02593+6016 / S 201 star forming region. A young star cluster is observed in this region, which contains different classes of young stellar objects. The near-infrared (NIR) color-color and color-magnitude diagrams are studied to discuss the nature of these sources. We have discovered the clumps of molecular hydrogen emission at 2.122 μm in the central region of S 201. These clumps are clearly seen along the diffuse emission in north-west direction from the main IRAS source, which are probably the obscured Herbig-Haro objects. High sensitivity and high resolution radio continuum images made with GMRT at 610 and 1280 MHz show an interesting arcshaped structure due to the interaction between the HII region and the adjacent molecular cloud. The ionization front at the interface between the HII region and the molecular cloud is clearly seen by comparing the radio, molecular hydrogen and Br images.
