The Stuart Police Department announced that it had arrested three after a report of inappropriate activity on a juvenile’s phone. According to SPD, a concerned mother reported possible illegal activity discovered on her child’s phone on September 11, 2024.

SPD detectives investigated allegations of inappropriate communication between the juvenile and several adult males. Detectives say they reviewed photos, videos, and social media accounts.

The suspects are accused of providing or offering to provide the juvenile victim with tobacco, alcohol, and other gifts in an alleged attempt to establish a relationship. Detectives allege that each suspect was aware of the victim’s age.
