A Danish court on Tuesday ordered a man to be held in custody on suspicion of issuing several bomb threats that led to the temporary evacuation of two Danish airports and two shopping centres, police said.
The 31-year-old, who is from the town of Slagelse about 100 kilometres south-west of Copenhagen, was arrested Monday, hours after the threats were made.
He pleaded innocent and planned to appeal the Naestved district court's decision to keep him in custody until November 9, prosecutor Susanne Bluhm was quoted as telling Ritzau news agency.
At the hearing it emerged he was a former Danish war veteran who suffered from post-traumatic stress disorder and other mental issues. She said he refused to undergo an evaluation, the report said.
In one of the emails he allegedly tried to portray himself as an Islamist, but the prosecutor said the probe had not provided support for this.
In addition to the threats, he is suspected of raising false alarms.
The threats resulted in the evacuation of Aarhus and Roskilde airports after police received near-simultaneous threats by telephone, Ritzau reported. Threats were also sent by email to hospitals and universities. Shopping centres in Roskilde and Slagelse were also cleared. Sniffer dogs searched the affected premises, and several hours later the police gave the all-clear.
Email threats that also targeted Copenhagen's main airport and two universities and a hospital were considered "groundless," so authorities did not order an evacuation.
