ANN ARBOR, Mich. -- A full-time National Guardsman toting

two unloaded M16 assault rifles was allowed onto the Michigan

Stadium field before the Michigan-Michigan State football game.

Security officials allowed the man into the stadium, where more

than 113,000 people had gathered, because his weapons were empty

and no ammunition was found.

A member of the color guard reported the impostor, who was

escorted out by police.

Brown said the unidentified man was compliant, and told officers

he used his uniform as a ruse because he wanted to attend the Oct.

9 game but could not get a ticket.

Diane Brown, a spokeswoman for the university's department of

public safety, told WJBK-TV that school officials do not believe

anything was done "incorrectly or improperly by police in any of

the checkpoints."

Brown declined immediate comment when reached on Thursday.
