We present spectra of the afterglow of GRB 021004 taken with WHT ISIS and VLT FORS1 at three epochs spanning 0.49-6.62 days after the burst. Alongside absorption lines from the host galaxy, we identify absorption in HI, SiIV and CIV with blueshifts of up to 2800km s-1 from the explosion centre which we assume originates close to the progenitor. We investigate the origin of the outflowing material and evaluate various possible progenitor models, in particular a binary progenitor consisting of a Wolf-Rayet star and hydrogen-rich companion.
