An unnamed woman, 71, and her husband, 81, started bombarding the house next door with repeated plays of the band's track Afraid To Shoot Strangers, sometimes keeping it going until 4am.

The woman said they felt forced to act after a "whistling noise" kept them awake, and she'd had to take sleeping pills to help ignore it. "We wanted to give them a taste of their own medicine," she told Swedish police.
