The Winklevoss twins have filed another lawsuit against Facebook, claiming that the money they had received in compensation during a previous lawsuit was not sufficient.
The twins previously filed a lawsuit against Facebook in 2008 and received $65 million in settlement.
Tyler and Cameron Winklevoss, who went to Harvard with Zuckerberg, claimed that their former friend stole the idea of making a Facebook like platform and presented it as his own.
According to The Daily Mail, in the new lawsuit, filed in the United States District Court for the Northern District of California, the twins claim they were misled about the actual worth of the social networking platform.
The lawsuit also accuses Zuckerberg of securities fraud and demands an unspecified amount of money. Facebook has dismissed the lawsuit by claiming in its legal filings that the twins were suffering from "a bout of settlers' remorse".
Zuckerbergs betrayal of the Winklevoss twins was dramatised in the blockbuster movie, The Social Network, earlier this year.
