Peter Scannell, the whistleblower who helped take down Putnam Investments, for alleged mutual fund trading abuses, on Monday filed a lawsuit against the Massachusetts Attorney General and the state itself seeking a bounty for his role in uncovering the scandal.

Scannell, 48, is suing to collect a reward under the state's False Claims Act, aimed at providing protection and financial awards to those who expose fraudulent actions that have an adverse effect on the cities and towns within the Commonwealth or any political subdivisions of the Commonwealth. The move comes after Scannell was denied a $15 million reward, which he believed he was entitled to as an informant.
