Authorities said a bomb disposal robot was brought to the scene Wednesday when a suspicious package was reported on a train at Copenhagen Central Station and a witness reported hearing a woman say, "Was the package placed correctly?" to a man, The Copenhagen Post reported Thursday.
The disposal robot discovered the package contained a car battery and windshield wipers.
A couple later contacted police and revealed they had placed the package on the train so it could be picked up by a friend when it arrived in Gothenburg, Sweden.
"The woman explained that her friend needed the items and they placed the package on the train to save the delivery costs," police representative Sajja Haider said. "They had agreed precisely where to leave it on the train so that the friend could find it."
Haider said no charges are being filed in the case.
