The statement said no further information will be released other than Smyth's medical condition.
Smyth is listed as a student studying manufacturing, engineering and technology at MSU.
He was found at the intersection of Warren and Pleasant streets after witnesses reported to police a person was lying in the street. Witness statements and a review of surveillance camera footage showed him hanging onto the back of the Late Night Express bus and standing on the rear bumper as it left the downtown Cherry Street bus stop. The bus went several blocks before he fell off.
