During the week of March 23–27, 2026, the Noblesville Police Department carried out a targeted online predator investigation designed to identify and apprehend individuals seeking to exploit minors.
Throughout the week, specially trained detectives posed as juveniles between the age of 13-15, and living in Noblesville, in online applications and websites. During this time, numerous individuals communicated with our detectives even after being informed repeatedly that they were interacting with someone underage.
This week’s investigation culminated with an operation Friday whereby two individuals were arrested after allegedly arranging meetings, and their actions demonstrated intent to engage in unlawful sexual activity with the perceived minor.
“The efforts during this investigation by the Noblesville Police Department, along with vital assistance of the Hamilton County Prosecutor’s Office, are a clear indication that we are actively pursuing those who attempt to lure and prey on children,” Chief Brad Arnold said. “Let this be a warning that we will be relentless in identifying and arresting child predators so that they cannot harm those that are most vulnerable.”
As a result, two Hamilton County men were arrested and transported to the Hamilton County Jail. Tyler A. Marcum, 26 and of Noblesville, was charged with Child Solicitation, a Level 4 Felony, and Sexual Misconduct with a Minor (attempted), a Level 5 Felony. Gregory A. Carter, a 40-year-old from Carmel was charged with Child Solicitation, a Level 4 Felony, Sexual Misconduct with a Minor (attempted), a Level 5 Felony and three counts of Neglect of a Dependent, a Level 6 Felony.
Noblesville Police remind that a a charge is merely an accusation, and the defendants are presumed innocent until and unless proven guilty.
