Following a request from the Danish Data Protection Agency
the National Commissioner of Police was asked to review the 443 Article 96 "alerts" (aliens to be denied entry to the Schengen area) placed on the Schengen Information System (SIS) by Denmark. It was found that "the reporting had been erroneous in 25 cases" (5.6%) as well as various other errors (a total of 68 are set out, 15%) including failure to update the data. Letter from Danish DPA
