"He became aggressive and called her a slag.”
Yasser Nawaz, aged 23, of no fixed address, received a suspended sentence after he reacted violently to his sister’s wedding plans.
He discovered that his sister had planned to marry and he had not been involved in the process.
Nawaz’s outburst left his sister traumatised. She even considered suicide a few days after the incident.
Blackburn magistrates heard that she had driven to a motorway bridge and planned to jump. She was talked out of it by a friend on the phone. The police took her away and to hospital.
Rachel Ottley, prosecuting, said the victim was at her home address with her mother and Nawaz when her prospective in-laws arrived.
Ms Ottley said: “They had knocked on the door to ask for her hand in marriage.
“The defendant was not happy about this because he had not been involved. He became aggressive and called her a slag.”
Nawaz was holding a baseball bat. He shouted that he was her brother and why had he not been asked about the wedding plans before smashing a mirror and a table.
He then said: “I wouldn’t be afraid to use a knife as my honour means more to me than my mother’s life.”
While the sister was not physically harmed, she was put in great fear.
Ms Ottley added: “She has been told she has suffered post-traumatic stress disorder as a result of this incident.
“A few days after she drove to a motorway bridge and was only talked out of jumping by a friend on the phone.”
Nawaz pleaded guilty to assault through fear of violence and criminal damage to property at the family home.
Zabair Afzal, defending, said his client had a traumatic upbringing and had witnessed violence by his father towards his mother.
He said: “His father left when he was just eight years old and he has taken it upon himself to become the head of the household over the years.
“He sacrificed his education to become the main breadwinner for the family.
“He had no issues with his sister’s choice of husband but he felt betrayed because she and his mother had not discussed this significant step with him.”
Nawaz was sentenced to 12 weeks in prison suspended for 12 months and ordered to do 100 hours of unpaid work and complete 15 days’ rehabilitation activity requirement.
He was also ordered to pay £200 compensation and £400 costs and made subject to a restraining order for 12 months which prohibits him from having any contact with his sister or entering Garbett Street in Accrington where she lives with her mother.
