BLUFFTON — A Harrod man is under investigation for suspicious activity that mirrors activity that led to his arrest in 1999.Around 7:30 a.m. Thursday, a resident of East College Avenue reported a suspicious man wandering through yards. An officer found a 47-year-old man walking in the area and determined he was not a resident of the area. “The report was an individual was walking through back yards,” Bluffton Police Chief Rick Skilliter said. “We continue to investigate his explanation.”In 1999, the man was convicted of illegal use of minor in nudity oriented material and registered as a sex offender, according to the Allen County Sheriff’s Office website.

According to court records, he told police in 1999 that he had been in the neighborhood and briefly got out of his car to jog around the block. He later recanted and admitted to videotaping women that morning.In his car, officers found a video camera and videotape. The videotape showed nude women in locker rooms and a tanning salon. Some of the women were underage. Additional pornographic material was found in his home.In the latest incident, police found no suspicious items. “We’re working with the prosecutor to determine what, if any, appropriate charges would be,” Skilliter said.A warning to residents was issued using the Nixle messaging system.
