A noisy neighbour who played blaring music by Wings and Pink Floyd into the early hours and sang "like a demented banshee" is facing eviction.

Nicholas Formosa was convicted of harassment after waging a war of attrition against a family in the flat below.

As well as singing and playing music - including Live And Let Die by Wings - Brighton magistrates heard he stamped on the floor, shifted furniture and was verbally abusive.

Formosa's neighbour Keir Cracknell, who lives with his wife and child, kept a diary between July 2001 and February 2002 detailing the problems.

At an earlier hearing, he told the court this included the defendant singing like a "demented banshee".

Formosa denied harassment but was convicted yesterday.

Amy Packham, defending, said her client could now be evicted by Brighton and Hove City Council and be deemed to have made himself "intentionally homeless", so losing his benefit entitlement.

Leaving court, Formosa insisted he was the wronged party. He said: "I don't think there was any proper evidence at all. I'm going to appeal."

But Mr Cracknell said: "I'm ecstatic. Justice has been done. This was mental torture."

Magistrates had heard Formosa, who was also accused of trespassing in his victim's garden, would stare at Mr Cracknell's wife Ritsuko. The couple's three-year-old son Akira dubbed the defendant The Naughty Man.

The court heard Formosa, 25, bore a grudge against the Cracknells when they moved into the council flat in Tisbury Road, Hove, three years ago. Magistrates were told the defendant believed he was entitled to a share of the property's garden.

Dominic Dudkowski, prosecuting, told the defendant: "You were sleeping during the day, staying up late at night playing loud music, stamping on the floor waking up his young child and driving him to despair."

But Formosa said his music was never louder than a television set and claimed Mr Cracknell was harassing him.

Miss Packham said: "There seems to have been a complaint from Mr Cracknell when he was quiet or noisy. He simply couldn't do anything to make Mr Cracknell happy.

"Clearly, Mr Cracknell was obsessing about Mr Formosa and was hell-bent on making an allegation of harassment."

However, chairman of the bench Derrick Stirling told Formosa: "We are satisfied that there was abuse directed towards Mr Cracknell in the period in question and this, together with the noise of the music, amounted to conduct that caused harassment."

Formosa was given a 12-month conditional discharge and warned not to threaten, abuse or insult the Cracknells, play music between 11pm and 7am or make an unreasonable noise at any time. He was told to pay £100 costs.
