The officer based in Blekinge had been reported on four occasions in the past for alleged misconduct at work. One of the previous reports was for sexual harassment for which he was acquitted.
He was also reported for official misconduct and for breaching professional secrecy.
It has since emerged that the local police authorities in Blekinge had been trying to dismiss him for over ten years but the National Police Board declined the requests.
His heavy usage of the same dating site, more than 3,500 times according to local newspaper Blekinge Läns Tidning (BLT), resulted in a loss of wages.
In January he was reported for allegedly sexually harassing a woman. Local media reported that he visited a female plaintiff to discuss sexual problems with his partner and added that he used the same dating site as the woman.
"Our assessment is that he shouldn't be working here. But it is examined by the board and isn't up the police authorities in Blekinge," Cecilia Lindström Johnsson, chief counsel of the Blekinge police told BLT.
She added that the incident has damaged confidence in the police and that he will be handed other duties when he returns to work.
Local media reported that the man's colleagues were shocked when they heard of the revelations.
"His actions make all the male police officers in Blekinge a subject of suspicion when they meet the public or when they receive a notification. A woman that meets us will naturally think 'is that him?'" said Jonas Nimborn, chairman of the Blekinge police federation.
The man is expected to return to work in the coming days.
