A man who attacked his next door neighbour in bed knocking out three of his teeth and breaking his jaw in two places was jailed for 14 months.
Patrick Kearney, 34, was ranting and raving as he woke up David Jowsey at 9.45am on a Saturday morning over something Mr Jowsey did not understand.
Without warning Kearney punched him squarely in the face.
Prosecutor Nigel Soppitt told Teesside Crown Court that mechanic Kearney continued to shout, but there was no explanation for what he had done.
Mr Jowsey, whose eight-year-old son was in the next room in their Hartlepool home, said in a victim statement that the shock attack on March 10 last year had a devastating effect on him.
He said that he was previously a very nervous person and he suffered from anxiety and panic attacks.
Stephen Constantine, defending, said Kearney had been suffering from trouble with his neighbours for some time, and all his efforts to keep matters under control had failed.
That morning he had returned home from fishing and his partner had complained to him “He’s been going on all night.”
Mr Constantine said: “He accepts he went in remonstrating.”
Judge Shaun Morris told Kearney: “There had quite clearly been some problems earlier causing distress to your partner and your child.”
Kearney, of Wordsworth Avenue, Hartlepool, was jailed for 14 months after he pleaded guilty to inflicting grievous bodily harm.
