Officers who answered the desperate call of the neighbour tried repeatedly to contact the 23-year-old woman whose flat it was, according to a report in the Berlin Kurier on Saturday.
But they could not get a response, and eventually decided to break in the door in an attempt to find out what was going on in the flat.
“You could hear the noise out on the street,” one neighbour was quoted as saying.
When the officers smashed their way into the flat they found nothing more dangerous than the vibrator which was doing its best on the floor.
Now the young woman is not only going to have to face her neighbours when she returns home – she will also have to pay for the smashed door, the paper said.
