Shane Sparks The Mug Shot

TMZ has obtained the mug shot of "America's Best Dance Crew" judge Shane Sparks -- taken moments after he was arrested and charged with 8 counts of child molestation last week.

Sparks' lawyer tells TMZ Shane is innocent -- and merely the victim of an extortion plot.

LAPD Detective John Eum tells TMZ the LAPD is still investigating and looking for other possible victims.
