(CNN) -- The FBI was searching Tuesday for an Arizona pediatrician who is accused of distributing child pornography.

The suspect, Emilio Luna, was arrested on child pornography charges but was allowed to be confined in his house before his trial, the FBI said.

On Sunday, Luna was allowed to leave his house wearing an electronic monitoring device to go to church. That night, police found Luna's abandoned car. Inside the car, police found bolt cutters and the monitoring device.

Authorities believe Luna may have fled to Texas, California, Illinois or Mexico, places where he has lived before.

Luna is accused of sharing child pornography on peer-to-peer networks, the FBI said.

Luna's neighbors, some whose children had been to the suspect's office, said they were shocked by the incident, CNN affiliate KNXV reported.
