Maricopa County sheriff's detectives said they believe there may be more victims after a Queen Creek man was arrested Thursday on suspicion of molesting two girls, ages 3 and 6.
Harold Whittle, 61, was booked on two counts of child molestation. He is being held without bond at the Fourth Avenue Jail.
Detectives said the investigation began Monday when the suspected molestations were reported.
As the probe widened, another victim living out of state came forward with similar allegations.
Detectives said Whittle, who is a grandfather of 16, was arrested in Utah in 2005 on charges of lascivious acts against a child living next door.
"This is the worst act against an innocent child a person can make," said Maricopa County Sheriff Joe Arpaio. "I don't care if he's a millionaire or if he has a private jet, he belongs in jail," says Arpaio.
Sheriff's investigators said there could be more potential victims. People with information about Whittle are urged to contact the Maricopa County Sheriff's Office at 602-876-1011.
