I've had obnoxious, noisy neighbors who have made me fantasize about using all kinds of noise-making devices in retaliation. (Instead I sent a letter to their landlord, and a month later they were gone.) But this guy, Brian Pemberton, took the harassment of his neighbor to an entirely new level:
victim Kathyrn McKay became a virtual prisoner in her own home in Baildon after Pemberton monitored her movements with a security system and triggered a "farting machine" to make loud noises every time she went out. He would press his naked backside against a window and expose himself to her and her young daughter while his laughing wife pointed. The father-of-two, who knew Mrs McKay had an eating disorder, would also make vomiting noises with the practical joke machine that she could hear inside her home...
Pemberton would shout out of the window that Mrs McKay was fat and ugly, and also taped offensive notices to the windows of his house and caravan including one that said: "Are you fat? Try Weight Watchers." She was also kept awake by loud banging on her bedroom walls at all hours of the day and night, which Pemberton claimed was made by his disabled daughter when she needed help in the night. Pemberton also terrorised Mrs McKay's daughter and on one occasion drove his car at her while she was on her bike. He doused fireworks in their garden with a hose as they tried to celebrate Bonfire Night. He was also accused of taping her phone calls and shouting out their personal information in the street.
It doesn't sound like his neighbor ever did anything to inspire this behavior from him. He simply took an irrational dislike to her. He was sentenced to 20 weeks in prison, which he has successfully appealed. He's also promised to move. I would hate to be his new neighbor.
