The suspect was arrested a few days after the robbery in cooperation with Swedish police and was subsequently requested to be extradited to Denmark.
On Thursday, it was decided that the man will be remanded in custody until March 12. He is suspected of aggravated robbery and attempted murder, reports Sjællandske Nyheder.
According to the newspaper, the arrested person denies any wrongdoing.
Pokémon cards worth at least 300,000 kronor, equivalent to just over 420,000 Swedish kronor, were stolen, according to the allegations.
