Police in Arizona are searching for a man they want to question after several students said their drinks were spiked at a JROTC ball.

The man, according to a Facebook post from police in Flagstaff, was spotted on surveillance camera lurking around a Double Tree Inn on March 11 while the Coconino High School JROTC was holding a ball. 

Police said the man was acting "suspiciously" and walking around "checking conference room doors" and "going up and down in the elevator near the lobby."

The man was confronted by a chaperone and identified himself as "Sgt. Major Travis Palmer" before saying he had to take a phone call and left the premises.
