An anonymous woman calling from Brussels on March 11 warned police that three men were planning to carry out a terror attack in an Ikea store and several other department stores in Amsterdam. She mentioned a family link to one of the perpetrators of the 2004 Madrid train bombings.
Following the tip, six men and one woman were arrested in Amsterdam and the shopping area near the Ajax football stadium was sealed off. Police released all seven suspects in little over 24 hours and no explosives were found in the stores or at their homes.
The 48-year-old woman arrested on Monday is being accused of making a false bomb and terrorism threat. She is due to appear before a judge in Rotterdam on Thursday.
A police spokesperson at the time said the caller was a woman who spoke Dutch with a French accent and seemed to be consulting with someone during the 10-minute conversation. After the threat of a terrorist attack in Amsterdam evaporated, police were criticised for using unreasonable force during the arrests and for going public with the Moroccan heritage of the suspects.
