Original story April 11:
The Blount County Sheriff's Office is crediting the public with help identifying seven suspects accused of damaging a radio transmitter.
The sheriff's office released photos Friday afternoon of surveillance photos of men who they believe did $61,000 worth of damage to a radio transmitter that provides key communication between deputies and park rangers in the Great Smoky Mountains National Park.
The vandalism was first suspected on Monday, when radio service for Blount County dispatchers became intermittent. On Tuesday, rangers discovered the damage to the radio equipment located near the fire tower on Foothills Parkway.
A large rock was found on the walk way to the fire tower, and other rocks were found on top of breaker boxes on the tower.
The damage has since been repaired.
The suspects' names have not yet been released.
