The FBI has revealed how thieves used high-tech gizmos to make off with gold bars worth $4.8 million in a truck robbery on Interstate 95 in North Carolina and it reads like a heist fit for Hollywood.

A year a go, a truck that was on its way to Massachusetts to deliver gold bars worth millions, was intercepted by three armed men near Wilson, North Carolina.

Agents say the armed robbers prepared for the job using a GPS tracker and a remote-controlled pepper-spray launcher to subdue the drivers.

Agents identified the alleged ringleader as Adalberto Perez, 46. He was arrested this week at his home in the Miami suburb of Opa-Locka, Florida, almost exactly a year after the March 2015 robbery in Wilson County, North Carolina. Two accomplices remain at large.

It appears the case was cracked when a friend of Perez came forward just a few months ago. According to an FBI affidavit unsealed in federal court this week, the friend said Perez spent about a year preparing for the heist.
