A man who was banned from having any contact with his mum turned up at her house for "a brew and a chat."
Blackburn Magistrates' Court heard Duncan Newbiggin was prohibited from having any contact with his mum by a restraining order imposed after he assaulted her.
The court was told there had been eight previous breaches of the order, the latest resulting in a custodial sentence.
Newbiggin, 48, of no fixed address, pleaded guilty to breach of a restraining order and was jailed for 16 weeks.
District Judge Alexandra Preston said it was the ninth breach of the order which had been put in place to protect his mother.
"She called the police because she clearly didn't want you there," said District Judge Preston.
"The offence is so serious that only a sentence of immediate custody can be imposed. This is the ninth time you have done it."
Scott Parker, prosecuting, said that before ringing the police the defendant's mother had locked herself in a room because he had started behaving erratically.
"He was in the house when police arrived, as was his mother, although she did not provide a statement," said Mr Parker.
John Rusius, in mitigation, said his client suffered a brain injury at birth and had significant mental health issues.
"He admits that on occasions if he needs something, he goes round to his mum's," said Mr Rusius.
"On this occasion, she was initially pleased to see him and they had a brew. She did call the police but then refused to make a statement."
