The National Forensic Centre, NFC, carries out technical examinations of everything from fingerprints to mobile phones.
The department has long been described as a bottleneck in the judicial chain and has also received criticism for, among other things, its handling of DNA traces and serious IT deficiencies.
Among other things, the internal audit came to the conclusion that there is a double leadership in that both the head of the NFC and the head of the police's National Operative Department, Noa, are responsible for the forensic activities.
The review was presented together with several measures that National Police Chief Anders Thornberg has decided on to address the shortcomings - above all, increased collaboration between NFC and the police's investigation activities to arrive at joint priorities and shorten the queues.
The manager's criticism: "Biased"
But there was one detail in the report that was not noticed in December: there were no names of the internal auditors who participated in the review.
The explanation: an infected conflict about the content of the report.
When the auditors' report was sent for fact-checking to the NFC, manager Helena Trolläng reacted very strongly, accusing the audit of being biased in favor of the police's investigative activities.
After several rounds, the head of the internal audit, according to SVT's sources, chose to take Trolläng's side in practice.
A sharp recommendation was deleted, that the police should propose rule changes to the government that would make it possible for the police management to change the NFC's organizational location.
The changes meant that none of the three auditors ultimately wanted to stand behind the report, which was thus published without a name.
The report was cancelled
Trolläng's actions were also reported by an accountant to the police's Special Investigations department, where the report was dismissed.
It is confirmed for SVT Nyheter by former SU head Ebba Sverne Arvill.
Helena Trolläng says she does not know that she has been reported.
She confirms her criticism of the report in a written comment.
She writes that she stands behind the independence of the internal audit, but that this does not mean that the quality or recommendations of the review cannot be questioned.
Internal audit director Peter Ambroson does not want to participate in a television interview but confirms that he changed the report contrary to the auditors' opinions.
He says that he considered that the auditors went too far in their writings but does not believe that he has given in to any pressure.
