The legendary investor Bill Gross has become entangled in a bitter legal feud with his Los Angeles neighbour over a $1m (£770,000) glass outdoor sculpture, a priceless clifftop view and an alleged campaign of musical harassment.

Mr Gross, once dubbed the “bond king” for his titanic holdings under his company Pimco, is accused by tech entrepreneur Mark Towfiq of embarking on a campaign of abuse that allegedly included deafening “nightly concerts” of pop songs, rap music and the Gilligan’s Island theme tune on loop, in a lawsuit filed on October 14.

In a parallel lawsuit filed the previous day, the 76-year-old billionaire accused Mr Towfiq of “peeping Tom behaviours” and invasions of privacy such as spying on him and his girlfriend, former professional tennis player Amy Schwartz, while they were swimming.

The focus of the dispute is a 22 foot long, night-lit $1m glass garden sculpture by the artist Dale Chihuly, and a large net enclosure built over the sculpture in order to protect it from damage.

It was the latter structure that reportedly led Mr Towfiq, head of the data centre company NextFort, to complain to the greater Los Angeles city of Laguna Beach about his view being spoiled – allegedly prompting a campaign of sonic warfare and the two lawsuits.

The dispute, unfolding between two sprawling multi-million-dollar homes perched on cliffs above the brilliant blue Pacific, has led to several police visits and applications for restraining orders from both sides.

Mr and Mrs Towfiq’s suit said: "William Gross is a 76-year old billionaire used to getting his way no matter what. As proven by their behavior here, Gross and his decades-younger girlfriend, defendant Amy Schwartz are bullies."

It described Mr Gross and Ms Schwartz as repeatedly dancing on their balcony to taunt Mr Towfiq, quoting a text message allegedly sent by Mr Gross: “Peace on all fronts or well [sic] just have nightly concerts big boy.”

Lawyers for Mr Gross, who is worth an estimated $1.5bn, claimed the entire dispute had sprung from Mr Towfiq's alleged "obsession" with him and his girlfriend, accusing them of vandalising the glass sculpture as part of a stalking campaign.

They said: "On numerous occasions, Defendant Towfiq has been spotted leering from his bedroom window, deck, and other places around his home at Plaintiffs and Plaintiffs’ family [and] taking photos and/or video recordings of Plaintiffs...

“Defendent Towfiq appears to have a particular fascination not only with Mr Gross but also Ms Schwartz, particularly when the pair are swimming and thus wearing minimal, if any, clothing.” Both sides have requested restraining orders.

Mr Towfiq's suit called those claims "completely false", saying that he had only recorded his neighbours in order to document their harassment, as well as accusing Mr Gross of calling him "boy", which it described as an "ethnically-charged epithet" in its context.

Rather than vandalism, it argues that the sculpture was probably damaged by falling vegetation. The Los Angeles Times reported that a representative of Mr Gross had told Laguna Beach officials that it had been damaged by a palm frond.

Mr Gross was previously accused, in his lengthy "war of the roses" divorce from his second wife Sue, of leaving a previously shared house to her in "utter chaos and disrepair", including by spraying it with a foul-smelling prank substance called Liquid Ass

The billionaire admitted to using fart spray in an interview last year, but claimed that he was responding to a similar alleged assault on another house by his ex.
