The Birmingham Mail has been handed an audio recording of two police officers talking while in their patrol car, where they branded domestic violence victim Alex Faragher, 19, a "f***ing slag".
Their remarks were unwittingly left on her mobile phone's voicemail.
The two police officers had arrived to take a statement from the teenager in Sutton Coldfield but she has complained that they rang her phone when they discovered she was not in.
When it went to answerphone, their expletive-ridden conversation was automatically recorded.
One officer is heard saying to his colleague: "F***ing bitch, I specifically said: 'You are not going to give us the runaround are you?'
"'No, I want to press charges,' she said.
"F***ing slag."
Later in the recording the officers can be heard checking addresses for the teenager from the police control centre.
The second officer is then heard stating: "Either that or the only other thing we do is go back, f*****g draft the statement ourselves and then just get the bitch to sign it."
Ms Faragher made an official complaint after listening to the recording, explaining the the Mail: "I could not believe what I was hearing.
"These two people were supposed to be coming out to help me and instead I received abuse"
"They did not realise that they had connected to my voicemail, which recorded all of the horrible things they were saying about me.
"These two people were supposed to be coming out to help me and instead I received abuse.
"What if this had been a rape victim and these kinds of comments were being used?
In a statement to the Mail, Rachel Jones, Commander of Birmingham North Police, said: "I have visited the complainant personally to explain what action is being taken as well as apologising for any upset caused as a consequence of the officers’ alleged conduct.
"Whilst professional standards enquiries are ongoing, the officers have been placed on restricted duties and in a non-public facing role."
