TMZ has learned the actor who played Random Task in the first "Austin Powers" movie has been charged with a vicious gang rape.

Joe Son's arrest has been all over newspapers in the O.C., but no one connected the dots -- that the suspect is actually Dr. Evil's henchman -- until now.

Here's how it all went down. Son pleaded guilty back in May to felony vandalism. The plea required him to fork over a DNA sample. Investigators ran his sample and found Son's DNA connected him to an unsolved gang rape back in 1990, where a woman was pistol-whipped, raped, threatened with death and eventually blindfolded and released naked.

Son has been charged with five felony counts of rape, two felony counts of forcible sodomy, two felony counts of sodomy in concert by force, seven felony counts of forcible oral copulation, and one felony count of sexual penetration by foreign object by force.

Son faces a maximum sentence of 275 years to life if convicted.
