Man charged with cellphone signal-jamming on CTA Red Line

CHICAGO (WLS) -- Police say they've arrested a man for jamming cellphone signals on CTA trains.

CTA officials say they've been investigating a number of complaints about Dennis Nicholl. Some riders took photos of the man using what appears to be a signal-jamming device.

Officers followed 63-year-old Nicholl onto a train at the Loyola station Tuesday morning and arrested him after they allegedly caught him in the act.

He faces one felony count of unlawful interference with a public utility.
