Analysis of data in the INTEGRAL archive shows that an outburst from the recently discovered source IGR J08408-4503 (Atel #813) occurred on 1st July 2003. The outburst lasted approximately two hours. During its brightest part (around 20 UT) an average flux of about 6x10-10 erg/cm2/s was detected in the 20-60 keV range with the IBIS/ISGRI instrument. The derived position (RA=130.1900 deg, Dec=-45.07037 deg (J2000), uncertainty of 2.6 arcmin) is consistent with that reported in Atel #813 and with the position of the supergiant star HD 74194. This detection makes it very unlikely that the outburst detected on May 15th 2006 was a long GRB and supports the interpretation of IGR J08408-4503 as a new member of the Supergiant Fast X-ray Transient class.
