In one incident, around 300 refugees, including large numbers of women and children, set off on foot for Sweden, forcing police to shut the motorway near Padborg for a several hours.
The migrants had been housed in an old school building after arriving in the town but took to the road, saying they wanted to travel north to Sweden.
Some elderly migrants called off their 180-mile trek to Copenhagen, the jumping-off point for crossings by bus, train or car to Sweden.
The refugees refused to register with Danish authorities, which would mean having to apply for asylum in Denmark or returning to Germany, preferring instead to seek asylum in Sweden, where asylum conditions are more generous.
Sweden, one of many European countries struggling with the worst migration crisis since World War II, has become a top EU destination for refugees by issuing permanent residency to all Syrian asylum seekers.
