A man whose son stabbed him after discovering he had downloaded child porn has been given a 36-month community order.
Brian Croft, 56, of Cedrus Court, Kingsthorpe, Northampton, was sentenced after admitting possession of and creating indecent images of children.
His son Martyn Croft was jailed for seven-and-a-half years in November also at Northampton Crown Court.
He had admitted repeatedly stabbing his father, a former bank worker.
Brian Croft was told the community order would also include his participation in a sex offenders' programme.
'Child porn images'
Croft, who is now unemployed, was also told to sign the sex offenders register, on which he must remain for at least five years.
The court heard how the attack led to a police search of Brian Croft's home - and the discovery of more than 10,000 child porn images on a computer and compact discs.
Most of the photographs were at the lower end of a scale used by police to categorise the seriousness of images.
But 13 were in the most serious, level five category, and 173 were in level four.
Children featured in the photos ranged in age from babies to younger teenagers, Northampton Crown Court was told.
Sentencing Croft, Judge Thomas Corrie said: "I have seen a few examples of the level four and five images, which I shall not describe save to say that they show unspeakable things being done to children.
"By far the most constructive sentence and best way to protect a vulnerable section of the public is the course I have followed."
The court was previously told how Martyn Croft, 31, of King's Heath, Birmingham, had driven to his father's house in January last year, angry at allegations of the older man viewing child pornography.
When he arrived in the early hours of the morning, he went to his father's bedroom where he stabbed him 16 times with a kitchen knife.
In mitigation, Derek Johashen, defending, said: "He (Brian Croft) feels very, very distressed that his behaviour has caused such significant problems within his family."
