The guy arrested for stealing $3 million worth of jewelry off Drake's tour bus got caught red-handed after getting really high, breaking into a woman's dorm room and offering her sex ... according to docs.
As we reported ... Travion King was arrested at Arizona State University Wednesday, but we've now learned he allegedly broke into a student's dorm room in the middle of the night. The woman said she woke up to King trying to climb into her bed, telling her he'd never been with a white girl ... and offered to "eat her out."
The woman freaked and ran to another room, where she and a friend called campus cops and had Travion arrested. Cops say King told them he'd been smoking weed and PCP, and broke into the dorm because he wanted to "smoke and f***" and was thinking with the "wrong head."
King was booked for criminal trespassing. Police also found a briefcase full of jewelry ... which linked him to the tour bus heist outside Drake's Tuesday night concert.
