Afshan, 22, was beaten last year, called a "whore," and reportedly threatened with death after her family found out she was seeing a young Hindu man. Reuters reports the beating also included being punched, dragged around by her hair, and strangled by her 28-year-old brother Ashraf Azad.
The assault took place at the family's home in Manchester, England. After the assault, both the brother and the father were found not guilty of making death threats, but Ashraf pleaded guilty to one count of assault.
Reuters says Afshan, who now lives in London, asked the judge in the case not to send her brother to jail. But judge Roger Thomas ignored that request, and instead sent Ashraf to prison for six months after he pleaded guilty.
"This persistent attack was accompanied by serious and very hurtful abuse and threats," the judge told Ashraf in court.
"The background to this offense lies in the concern that you, and perhaps other family members, had about Afshan's relationship with a young man who was not of the Islamic faith."
Afshan played a classmate of Harry Potter in several of the blockbuster Hollywood films.
