Bomb squad called to Princess Mary's Danish home Amalienborg

A woman has been arrested after allegedly sending a suspicious package to Princess Mary's Danish home Amalienborg Palace in Copenhagen.

The bomb squad was called in on Tuesday and parts of the palace - specifically the Yellow Palace next door to the family's main residences – were sealed off just before 9am when a package was sent.

According to local reports, the Armed Forces' Ammunition Clearance Service was called in to investigate the item, using two remote-controlled robots to determine the contents of the package.

Tests were also carried out on the suspicious package, with the area remaining cordoned off for a number of hours.

Photos show police and emergency workers gathered at the scene, before the item was deemed harmless.

By 3pm that afternoon police confirmed a 57-year-woman had been taken into custody in Ribe, a Danish town, and arrested in connection with the scare.

She was charged with making threats against the royal family.

Luckily Crown Princess Mary, Crown Prince Frederik and their four children were not home at the time of the threat.

They live within the Frederik VIII's Palace - the Amalienborg complex has four palaces – but are staying at Fredensborg Palace, north of Copenhagen, during the summer.

Queen Margrethe is also currently based at Fredensborg Palace.

But her sister Princess Benedikte was inside her residence within the Christian VIII's Palace at the time of the threat.

The palace has not made any further comment about the incident, which is very similar to one that occurred at Queen Elizabeth's official residence in Edinburgh, Scotland.

A man was arrested after a suspicious item was found in March, at the palace of Holyroodhouse. According to reports the suspect is believed to suffer from mental illness.
