A Chicago individual has been taken into custody for utilizing a cell phone jammer during a train journey.

He's a silent avenger.

Dennis Nicholl, who serves as a financial analyst at the University of Illinois Hospital in Chicago, was arrested last week for accomplishing a goal shared by numerous commuters around the globe: the silencing of cell phone calls.

The significant saga unfolded in late 2015 when residents of Chicago reported their mobile phones either dropping calls or experiencing complete service outages while on local trains. The individual behind this disruption was later identified as Nicholl, after Chicago IT employee Brian Raida posted a photo on Reddit that depicted Nicholl with a cell phone jammer in one hand and a beer can in the other. This illicit device is capable of incapacitating cellular and radio signals within an entire neighborhood.

In a statement to the Chicago Tribune, Aaron Robinson, who saw Nicholl behind the wheel, stated, "I suspect he appreciated the sense of authority that came with driving the car. Its somewhat reminiscent of a digital version of the phrase, 'You young people with cell phones, get off my lawn.'"

On March 8, the Chicago Police Department, in conjunction with the Chicago Transportation Authority and the Federal Communications Commission, carried out an undercover operation that resulted in Nicol being caught in the act. He faces felony charges due to the signal jammers' ability to disrupt police communications and block emergency calls. Consequently, he may face imprisonment and a fine of up to $100,000.

Much to the chagrin of many, residents of the Windy City have regained the freedom to make personal calls while on the go.

With respect to Nicol's reasons, he emphasizes that he merely sought to travel in a serene manner.
