To an Arizona middle school, Batman! Three schools in the north Phoenix suburb of Cave Creek were on lockdown for about 45 minutes Wednesday morning after a student at Desert Arroyo Middle School reported seeing a person dressed as Batman run across campus, jump a fence and disappear into the desert, Scottsdale police Sgt. Mark Clark said.

The student described the person as 6 feet 3 inches tall and possibly male.

"We're assuming it was male, although they did have a mask on," Clark said.

Officers combed the desert around the middle school. A nearby elementary school and high school also were on lockdown as officers sought the caped crusader.

The result — no Batman.

"It's just one of those interesting little stories that we looked into but we couldn't find anyone," Clark said.

Nedda Shafir, a spokeswoman for the Cave Creek Unified School District, said putting all the schools on lockdown was a precautionary measure.

"We didn't want to take any chances," Shafir said. "We just don't want to put anyone at risk."
