Underwater footage, which the newspaper released after several accounts of the incident, show that at least 50 metres of the pipeline is missing at a depth of about 80 metres.
The pipe's metal was also severely deformed in parts and there were rips and deep cracks in others, Expressen reported.
"Only extreme force can bend such thick metal in this way," Trond Larsen of the company Blueeye Robotics, who directed the underwater camera for the newspaper, said.
Swedish authorities have already investigated the damaged pipeline within the Swedish economic zone and secured the necessary evidence.
Danish police confirmed on Tuesday that the damage to the Nord Stream pipelines in Denmark's economic zone was caused by "powerful explosions," according to internal investigations.
In collaboration with the Danish domestic intelligence and security service PET, Copenhagen police plan to form a team of investigators.
A statement said that it is too early at this stage to determine the extent of international co-operation which will take place, perhaps with countries like Germany and Sweden.
At the end of September, four leaks were discovered in the Nord Stream 1 and 2 gas pipelines following explosions near the Baltic Sea island of Bornholm, two each in the exclusive economic zones of Denmark and Sweden.
