A vegetarian couple accused of stalking their ex-neighbours claim they had to call police due to intense "rotten meat" smells from next-door.
Senior restaurant sommelier Christoph Hons, 50, a wine and beverage expert at Mayfair's Park Chinois told the jury his career makes him particularly sensitive to taste and smells.
He and wife Sylvia Hons, 45, an architectural technician both of Westmorland Close, Twickenham deny stalking Scott Lawrence and his wife Jessica Parker between January 15 and April 29, last year.
They are accused of filming their former next-door neighbours on their mobile phones while observing from local cafes.
Scott and Jessica moved half a mile away after repeated run-ins with the Hons', who also complained about late-night parties, loud banging, drilling and dog-walking to the side of their property.
"Your home is full of this bad smell, in the curtains, in your clothes, all over the place," Mr Hons told Kingston-upon-Thames Crown Court.
"It was very intense, foul meat, rotten meat. I am quite sensitive on taste and smell, it is a big part of my job.
"We called the police every time that happened. Every time it occurred."
The couple traced the smells to a service pipe between the two homes and installed insulation in the area, which successfully combated the odour.
Both couples ended up filming each other with their phones and Go-Pro's and Christoph, whose home is equipped with multiple CCTV cameras, was issued with a police harassment warning along with his wife and Mr Lawrence.
Earlier Jessica told the jury: "They tried to attract our attention to film us. I'd see them out of the corner of my eye.
"I knew they didn't want us to be in the garage area, but it was useful to us. We would throw a ball to the dogs and nobody else minded.
"Eventually they got a 'No Dog Walking' sign put up there.
"We had been exercising our dogs and Mrs Hons went back home to get her moped and drove it at us for half an hour, while filming.
Sylvia claims Jessica was enjoying the confrontation and "smiling" because one of her dogs was barking at her, but the complainant says her dog was agitated by the deliberate moped revving.
Mr Hons told the jury loud weekend parties began taking place in late 2015. "We could hear the music through the walls up until two or three am.
"I complained, but I found them quite aggressive so reported the noise to their landlord. The parties stopped, but then they started throwing things at the walls and there was loud banging of doors up to midnight.
"There was also six weeks of continuous drilling. You could feel the vibration through the wall. It was getting very annoying."
Mr Hons told the jury he and his wife reported his neighbours to Richmond-upon-Thames's Environmental Health department because of the constant noise.
He denied "laughing and abusing" his neighbours as they walked past, giving them 'the finger' and damaging one of their vehicles.
Mr Hons insisted he would go out of his way to avoid confrontation in the street. "I would go behind a bush or a car to avoid contact with Mr Lawrence.
"By that stage I was in a kind of fear and anxious about him. My cameras were to monitor and prevent an incident because I did not know how far it would go.
"He once said: 'I'm going to get you, I'm going to slap you.' He was very aggressive.
"I was shocked. We never gave him a reason to do that. I feared for the safety of myself, my wife, my house and my cat.
"It was frustrating that the police really didn't do anything to resolve this situation."
The trial continues.
