Two police officers wrestled a man to the ground and stamped on him after mistaking him for a missing Alzheimer's patient and refusing to listen to his protests because of his Welsh accent.

PCs John Richardson, 50, and David Littlemore, 35, both based in Thorpe Wood, Peterborough, were today convicted of beating John Morgan, 59, while he was sitting on a park bench with his dog.

The court heard how the officers were out looking for a man in his 70s with dementia who had disappeared from his home with his pet in August last year.

Mr Morgan, who has poor sight and diabetes, was with his Jack Russell, Winston, when the pair approached him.

He told them he wasn't the missing man but refused to give them his name and address, leaving Littlemore suspicious that he was putting on an accent.

Mr Morgan told the court he was then 'dragged to the floor' by Littlemore and Richardson, who twisted his arms behind his back.

His phone and glasses fell to the ground and he said Richardson repeatedly stamped on his right hand, Luton Magistrates' Court was told.

Mr Morgan was only released when Littlemore confirmed via his radio that the missing man's dog was a Staffordshire Bull Terrier type - not a Jack Russell.

The retired engineer told the court earlier this month: 'Officer two on my right [Richardson] wrenched my thumb back from my index finger and tried to get the dog lead out of my hand.

'He then stamped on my hand repeatedly and a lot of pressure was put on my back by officer one [Littlemore]. It could have killed me.

'I remember asking them about my human rights and taking their collar numbers which I forgot and being very disorientated.

John Moran, outside Luton Magistrates' Court at an earlier hearing, said the officers 'dragged him to the floor' and 'stamped on his right hand'

'I remember officer two [Richardson] saying he 'did not care' repeatedly about my vulnerability.'

The missing man, Bill King, was described as wearing a hat, check shirt, brown cord trousers, brown shoes and had a black and white dog with him.

Mr Morgan was described as wearing a similar outfit, also with a black and white dog, but wearing black combat trousers.

It was confirmed in a radio conversation between PC Littlemore and another officer that the missing man did not have a Welsh accent.

The correct missing man was found later that day and Richardson assisted in taking him home to his family.

Littlemore, of Wittering, Cambridgeshire, and Richardson, of Kings Cliffe, Northamptonshire, both denied assault by beating, but were found guilty by the judge earlier this month.

Sentencing them today, District Judge Susan Holdham gave both PCs three months in prison, suspended for two years, and fined them £1,030 each.

She said: 'I have heard a lot about how stressful and difficult this time has been for the officers. You have both lost good character and probably whatever the sentence you will lose your employment.

'However, I remember what I saw at the trial. I saw a man who was, if not actually frail, but certainly not robust.

'A man with various ailments and although not related to the case with diabetes and have part of his foot amputated. He was a man minding his own business with his dog that day you came up to him.

'You asked him for his name and address as you thought he might be the missing gentleman with Alzheimer's.

'When he refused he was brought to the floor, he was punched, constrained, had his thumb bent back to release a dog lead and hand stood on.

'I still find it very difficult to understand what was going through your minds that day. You could have thought he was a vulnerable man who said he needed safeguarding.

'And to this day I do not understand how taking a man like that to the floor is safeguarding.

Both officers (Richardson, left, and Littlemore, right) were given a three month prison sentence, suspended for two years at court today

'I saw Mr Morgan was very reasonable and particularly depressed as he had to have his foot amputated since.

'This happened because he did not give his name and address and he was dealt with as if is some kind of police state and taken to the floor for not giving their name and address.

'He was either a 76-year-old man with Alzheimer's or he was an innocent man who refused to give his name and address.

'It is vital society has faith in their police officers and society is entitled to look to police officers to use their powers responsibly and that was not done that day.'

Mike Humphreys, prosecuting, told the district judge in Luton the PCs had 'no legal authority to do what they did.'

District Judge Holdham agreed and said Mr Morgan had every right to free himself from PC Richardson holding his arm.

She ordered Richardson to carry out 200 unpaid work and Littlemore is required to complete 150 hours' unpaid work.

Both were ordered to pay £1,030 - £450 compensation to Mr Morgan, costs of £500 and a victim surcharge of £80.

Littlemore, whose parents, wife and sister were in court, has 10 years service with Cambridgeshire Police and Richardson has been with the same force for 18 years.

Richardson and Littlemore, who have been suspended from duty and will face internal misconduct proceedings by Cambridgeshire Police, both refused to comment as they left court.

Det Supt Mark Hodgson, head of Bedfordshire, Cambridgeshire and Hertfordshire Professional Standards Department, said: 'We want the public and our own employees to feel confident about raising concerns about the conduct of our officers and staff and we will always investigate these cases thoroughly and ensure prosecutions are brought where appropriate.
