In an informal investigation conducted at the scene, Mr. A said, ``The neighbor's house had set up karaoke equipment and was singing songs all night long.''

Mr. B, who lives next door, said, ``We spent a lot of money installing soundproofing,'' and ``I was told to sing from the house next door.''
I sang it,'' he said. A police official said, ``There was a dispute over noise-related issues, and both parties reported each other for assault,'' and ``Both parties are currently under investigation.''
