Hørs editor-in-chief denied that any of the hospital's employees had received payment from, or leaked information to, the magazine. After an internal investigation, the hospital concluded that the leak had probably occurred via a third party. The singer Rasmus Nøhr described an experience following his searching by police that he believed could indicate leaks from the police to Se og Hør. Henrik Qvortrup told the police that the magazine had sources at the police, the army, Copenhagen Airport's control tower, and amongst nurses. Several then-current and -former Se og Hør employees additionally described how, prior to October 2003, the magazine had plans to purchase bugging and listening equipment. This would have been used to access Prince Frederik's telephone but Qvortrup insisted that the plans were abandoned.

In the days immediately following the breaking of the scandal, the police visited both IBM and Nets to investigate whether any offences had been committed. However, they were unable to determine whether a crime had taken place. IT equipment was seized from Aller Media, which led the organisation to fear that the police would identify other sources that had been used by its child publications throughout the years. The police interviewed Ken B. Rasmussen under the same procedures as if he were a suspect. Morten Helveg Petersen, then Det Radikale Venstre's candidate for the European Parliament, additionally reported Aller Media to the police. A number of other celebrities that had allegedly been monitored also made police reports via the lawyer Brian Werner Larsen. These initially included Casper Christensen,
