A Dutch former top banker who came under fire for taking a large pay-off after the nationalisation of his troubled bank was found dead along with his wife and daughter on Saturday in what police called a family tragedy. Jan Peter Schmittmann, 57, ran the domestic operations of Dutch bank ABN Amro between 2003 and 2007 and was widely criticised for landing an 8 million euro pay-off after the bank's collapse and subsequent nationalisation.
