Gubernatorial candidate Oz Griebel’s former campaign manager, Kyle Lyddy, was arrested by the Norwalk Police Department and charged with stealing $500,000 over a two-year period from a local marketing company where he was once employed.

Chris Cooper, a spokesman and the Griebel campaign’s new campaign manager, said Lyddy resigned Monday citing “personal reasons.”

The Norwalk Police Department’s Detective Bureau Fraud Unit investigated a complaint from a local company for a month, according to a police press release.

Lyddy, 31, is a Danbury resident. His brother, Chris Lyddy, was a state representative from Newtown from 2008 to 2012.

Lyddy was charged with first degree larceny and posted a $100,000 bond. He is expected in court on Sept. 19.
