A Westport man faces numerous charges linked to insurance fraud that police said he carried out, in part, by misusing the identity of a former business partner.

Darrid Sharkey, 40, of Roseville Road, turned himself in Tuesday after learning a warrant had been issued for his arrest on charges in connection with a scheme that police said said involved fraudulently billing the Aetna insurance company for client services he was not licensed or trained to provide during 2013 and 2014. A complaint about the suspected fraud was filed with police last Dec. 29.

Sharkey is believed to have defrauded more than $86,000 from the company through the scheme, police said.

The investigation by local police detectives, in conjunction with Special Agent John Gasiorek of the National Insurance Crime Bureau, showed that Sharkey continued to bill the insurance company after he and a partner had dissolved their business, according to the report. Afterward, police said, Sharkey continued using the personal information of his business partner, who was a state-licensed clinical social worker.

Sharkey was charged with first-degree larceny, criminal impersonation, first-degree identity theft, second-degree harassment, conspiracy, insurance fraud and third-degree forgery.

Bond was set at $250,000 bond and he is scheduled to appear Aug. 20 at state Superior Court in Norwalk.
