Observations of the Spitzer extragalactic First Look Survey field taken at 610 MHz with the Giant Metrewave Radio Telescope are presented. Seven individual pointings were observed, covering a total area of similar to 4 deg(2) with a resolution of 5.8 x 4.7 arcsec(2), PA 60 degrees. The rms noise at the centre of the pointings is between 27 and 30 mu Jy before correction for the Giant Metrewave Radio Telescope (GMRT) primary beam. The techniques used for data reduction and production of a mosaicked image of the region are described, and the final mosaic, along with a catalogue of 3944 sources detected above similar to 5 sigma, are presented. The survey complements existing radio and infrared data available for this region.
