Man accused of interfering with 'L' cellphone service

CHICAGO (AP) - A Chicago man has been charged with interfering with cellphone service on the city's 'L' trains by using a signal jamming device.

Authorities say Dennis Nicholl was arrested Tuesday at a stop on the Chicago Transit Authority's Red Line and charged with felony unlawful interference with a public utility. Undercover police officers made the arrest after receiving a tip.

Police say the arrest follows an investigation of complaints by CTA 'L' passengers about cellphone reception on the CTA. Transit officials, Chicago police and Federal Communications Commission investigators were involved in the probe.

Nicholl is scheduled to appear Wednesday in Cook County Circuit Court. It wasn't immediately known if he has obtained legal representation.
