On the evening of 11 February 1941, the day on which the fightings were on the Waterlooplein, some twenty young men were arrested by the Ordnungspolizei for their alleged part in these events. Most of them were released shortly afterwards. David Estella Zilverberg was brought to camp Amersfoort and then deported to Mauthausen.
