In a press statement, police said they were currently unable to provide information about what was discovered during the examination and search of the UC3 Nautilus submarine.
Kim Wall, 30, vanished after having boarded the 18-metre Nautilus sub on Thursday evening, apparently as part of her work on a feature story about its owner, inventor and entrepreneur Peter Madsen.
Madsen alone was brought back to a harbour on Copenhagen on Friday after the vessel sank in waters near Køge Bay.
The Swede's body was not found inside the submarine after it was raised and brought to Copenhagen for examination.
46-year-old Madsen is accused of negligent manslaughter and was on Saturday remanded in custody for 24 days.
Swedish and Danish authorities are now cooperating on the search for the missing reporter.
“We are currently being assisted by Swedish police, who are calling for any witnesses from the Swedish side of the Öresund and the Køge Bay area regarding whether they have seen the submarine. Information gathered in Sweden will be handed over to Copenhagen Police on an ongoing basis,” the police statement said.
Police said that nearly 300 people have contacted them regarding the case, many within the past 24 hours.
A significant amount of photos and video clips of the submarine in connection with its sailing out into the Öresund Thursday evening have been received, police said.
“We would still like to ask the public for help in order to determine the whereabouts of the submarine and receive knowledge of the dives it conducted,” the statement read.
“Currently, we know that the submarine sailed out Thursday the 10th of August at approximately 7pm, and that it was sailing in the area around Middelgrund for the next hour or so. The latest photo we have received from witnesses was taken at approximately 8:30pm,” police wrote.
Police also confirmed that the submarine passed close to a merchant ship around midnight between Thursday and Friday in the same area, as was reported by Swedish tabloid Aftonbladet on Monday, after a witness contacted the newspaper.
This was the last sighting of the submarine until Friday the 11th of August at approximately 10:30am in the Køge Bay, police also confirmed in the statement.
“We would still like to speak to possible witnesses who have information on the submarine’s sailing and dives in the time from 8:30pm until midnight and again from midnight until Friday at 10:30am,” the press message read.
“Currently we have no further information and will not be giving interviews,” police added.
