  The discovery of the high-ionization [Ne V] 3426A emission line in the
spectrum of the blue compact dwarf (BCD) galaxy Tol 1214-277 is reported. The
detection of this line implies the presence of intense ionizing X-ray emission
with a luminosity in the range 10^39-10^40 erg/s. Such a high X-ray luminosity
cannot be reproduced by models of massive stellar populations. Other
mechanisms, such as fast shocks or accretion of gas in high-mass X-ray binaries
need to be invoked to account for the high intensity of the [Ne V] 3426A
emission line.
