The 35-year-old attacked his girlfriend in the early hours of Monday morning in Landskrona, southern Sweden, according to the TT news agency.
“He has stabbed his partner in the breasts so that the silicone has leaked out,” said Nils-Erik Svensson, of the local police to the Helsingborgs Dagbladet newspaper.
Police managed to arrest and detain the man at 2.30am.
The woman, who is in her forties, was taken to hospital in Helsingborg where her injuries have been labelled by the emergency services as “not life-threatening”, wrote the paper.
It is believed the couple was fighting before the stabbing, and that the first call was made to authorities at 1am.
According to the officers, the man was already well-known by the police and had been for “many years” after repeated instances of violence.
The 35 year old man is now suspected of aggravated assault, and is set to appear in court on Monday.
