Members of the North Charleston Harbor Patrol Unit recently assisted the FBI and Lexington County Sheriff’s Department with a training class on Lake Murray. The FBI’s Post Blast underwater bomb technician class teaches local departments how to recover and collect evidence from an explosion on or in the water. Once collected, technicians can reconstruct the explosive device to determine what was used in it. This training and networking helps keep the citizens of the city and the Charleston Harbor safer. The NCPD Harbor Patrol Unit assisted in transporting divers to locations and providing security/safety zones.
