Florida man accused of using cell phone jamming device on I-4

(WFLA) A Florida man is facing a large federal fine for using a jamming device to block phone calls.

The Hillsborough County Sheriff's Office assisted in the investigation.

Major Clyde Eisenberg says deputies teamed with investigators from the Federal Communications commission to track down Jason R. Humphreys.

"This device is highly illegal. It's illegal by state law and also by federal law, and nobody has any business owning one of these things," said Eisenberg.

Eisenberg says federal authorities noticed that one cell phone tower near I-4 was being affected every day at the same time. The tower is owned by Metro PCS.

Eisenberg says when deputies tracked down Humphreys, they made a disturbing discovery.

"The first thing that happened is the deputy's radio shut down. This device shuts down all public safety communications and radios. The deputy was unable to communicate with his partner who was also assisting," said Eisenberg.
