Edward Lovett’s poultry farm was scoured by around a dozen officers in a crack operation involving a police helicopter.

The dramatic scenes unfolded on the outskirts of Bridge of Weir where Mr Lovett runs a poultry farm, breeding rare Black Rock chickens.

The 69-year-old is the grandfather of disabled teen Harry Lovett who last week issued a heartfelt plea for his dad Calum to get in touch before he goes blind.

The 17-year-old is a celebrated judo athlete but his biggest fight involves a race to complete a bucket list of wishes before the illness takes its ultimate toll.

His latest ambition is to be re-united with his father whom he hasn’t spoken to in over two years. And now the Lovett family has suffered another shock at the revelation that the farm owned by Harry’s grandpa Edward has once again been targeted by police in a major operation.

The latest raid comes after the conclusion of a long-running trial at Paisley Sheriff Court that ended with Edward being found guilty of neglecting his birds. During the case, the pensioner protested his innocence but Sheriff Colin Pettigrew wasn’t convinced and fined him £400 when the matter came to an end in May.

Mr Lovett claimed earlier in the trial that when police turned up at his property in July 2012 they were involved in a fruitless search for drugs and firearms.

The businessman, who also sells fireworks, told the court: “The police were searching everything. They were searching the sheds. They had a dog there for sniffing out drugs.

“That was one of the things they thought I might have.

“They had a gun dog there as well — sniffing for guns – which kept getting confused with my fireworks and gunpowder.” During his stint in the witness box he also revealed the strain the court case had caused him and his business.

He said: “It’s been a disaster. Various places will not take my birds because of this case. We have lost considerably financially.” The latest raid on R&A Lovett, Crosslee Road, took place on Tuesday, October 20.

A Police Scotland spokesman confirmed a team of plain-clothed and uniformed officers carried out an extensive search of the property for several hours.

They swooped at 9.30am with a helicopter flying over head in support before standing down at around 12.30pm following a “negative result”.

A statement issued by Police Scotland read: “We can confirm that on October 20, 2015, and April 4, 2015, police attended a farm on Crosslee Road, Bridge of Weir under warrant. On both occasions no criminality was established. In all cases where criminality is suspected, police will investigate appropriately.” The Gazette visited Mr Lovett’s farm to ask if he would like to comment on the latest raid but an employee told us he was unwell. He never replied to subsequent phone calls.

However, a friend, who did not wish to be named, described Mr Lovett as “a respectable man” and said he was “at a loss” to understand why the police were there at all.

He said: “I can vouch for Eddie. He is a stand-up guy and he has really suffered since the court case.” Meanwhile, his grandson Harry is slowly losing his vision and suffers from a number of health conditions including cerebral palsy, autism, dyslexia, epilepsy and impaired hearing. Medics have warned that his condition is already beginning to deteriorate, and that he is likely to lose his sight for good.

Instead of letting it affect him, defiant Harry compiled a ‘bucket list’ of the things he hopes to see and experience before he goes permanently blind. But one of the most heartbreaking wishes on his bucket list is a plea to his father Calum.

Father-of-two Calum Lovett ‘vanished’ from his family home in Bridge of Weir on October 25, 2013 and hasn’t been in touch with his family since.

Speaking on behalf of Harry, sister Bryony, 18, said: “When my dad first disappeared, Harry thought he was dead.

“But we have since heard that he is alive, which we are glad of, but we would rather he was alive and in our lives.

“Our dad has missed so many of Harry’s achievements over the last few years, which is sad because he should be a part of them.” Harry’s achievements include being nominated by the Royal Blind School to take part in this year’s Relay, scooping silver in the British Judo Championships and having won Gold in the Swimming Nationals.

Harry’s mum, Fiona, 42, made a desperate appeal for the father of her two children to get in touch and let them know he is safe.

When asked about the raids at Edward’s farm, she said: “Although Edward Lovett is Harry’s granddad, he is not part of our lives.” Additional reporting: Lisa Boyle and Rory Cassidy
