The state Attorney General’s Office announced the start of a statewide Sandy Fraud Working Group on Thursday to review investigations and prosecution of criminal and civil fraud related to Hurricane Sandy and receiving disaster funds.

The group will coordinate all investigative and enforcement efforts at the state, county, and local levels “to ensure all cases are referred and prosecuted as efficiently and effectively as possible,” the office said.

Victims or witnesses of fraud - including home repair fraud, insurance fraud and fraudulent charitable solicitations - should contact the organization at 855-SANDY39 (855-726-3939) or www.StopSandyFraud.org.

The group will also work with the state Comptroller’s Office, which announced Thursday it launched a website designed to allow the public to track state contracts and expenditures involving federal Sandy-related funding.

The website contains copies of the Sandy-related contracts, vendor information and details about available federal funding.
