After the attack, Cryne was taken to the Manchester Royal Infirmary hospital where she was treated for multiple stab wounds to her arm and shoulder.
Khan was arrested by police at St. Mary's Hospital, where her sick 1-month-old baby was undergoing treatment after being born prematurely.
Khan's baby later died.
Khan gave birth to the baby, Aydin, in March 2015. However, he was born 24 weeks early and had to stay in the hospital.
Khan later discovered her husband had been having an affair with Cryne while she stayed at a hospital with their ill infant.
Court documents revealed the knife attack came after Khan confronted Cryne in a series of hostile phone calls.
During one of their phone conversations, Cryne said, "I hope your son dies and when he does I'm going to dig him up and spit on him."
Khan responded to her husband's mistress, saying, "Watch it - when I see you, God help you."
On April 10, 2015, Cryne's brother Liam called the police to report his sister had been stabbed outside an apartment block.
According to the prosecutor, Vanessa Thompson,
Cryne spent two days in the hospital after suffering lacerations to her right shoulder, left arm and head in the attack.
Khan was taken into custody on April 11, despite telling police she had been in the neonatal department at the time of the knife attack.
During the hearing at Minshull Street Crown Court in Manchester, Thompson stated,
Khan's lawyer, Richard Lees, defended his client, saying,
During sentencing, the judge, Recorder Amanda Yip QC, told Khan,
Yip spoke about the negative effects the attack had on Cryne,
The judge also took Khan's mental state into account, saying,
After confessing to charges of wounding with intent and failing to answer bail, Khan was sentenced to three years and four months in a young offender institution and was ordered to stay away from Cryne indefinitely.
