Exclusive:Father of newborn baby followed female student through Sheffield city centre into subway before sex attack
Beinur Mustafa was seen “disappearing” into the subway behind his victim moments before the onslaught
The father of a newborn baby followed a “vulnerable” female student through Sheffield city centre into a subway before pulling down her clothes and sexually assaulting her, a court heard.
Beinur Mustafa, 35, was seen “disappearing” into the subway behind his victim at around 5.30 on February 4 moments before the onslaught.
As he groped his victim on the floor her screams brought help from nearby residents and he fled, however he was eventually traced and arrested through CCTV and bus records.
During a police interview he tried to flee after using the toilet - striking a female constable to the face and “strangling” her when she gave chase.
In a statement read to the court the sex assault victim, a masters student, described being “constantly anxious now” and her partner had needed to stop working to care for her, such was her level of trauma.
Jailing Mustafa, Judge Graham Reeds KC told him both of his victims being females was “not” a coincidence.
He added: “This is a particularly serious offence which brings to the fore the need to protect the public and deter others from doing the same.”
Describing the awful attack, Nicola Quinney, prosecuting, told Sheffield Crown Court: “The sexual assault took place on February 4, 2026 at just after 5.30pm.
“The victim had been at work and was walking through the city centre to go and meet friends at their flat.”
As she walked through a subway at St Mary’s Road the woman became aware of the defendant walking behind her, said Ms Quinney.
The prosecutor added: “So she stopped to look behind her and the male did the same and she continued walking.
“There’s CCTV that shows the defendant walking through the city centre following (the victim) for a period of time and then disappearing into the underpass.”
As the complainant emerged from the subway onto Charlotte Road she felt someone touching her bottom in a “patting motion”, said Ms Quinney.
“The defendant then grabbed the back of her leggings and underwear and pulled them down - that action exposed the top half of her bottom and she tried to pull them back up and turned to face the defendant.”
After pushing the woman to the floor Mustafa pulled the terrified woman’s leggings all the way down and sexually assaulted her.
As the woman screamed nearby residents ran out from their homes to help and sex pest Mustafa fled, said Ms Quinney.
After he was tracked down and arrested thanks to CCTV and bus records he also struck female detective constable to the face and “strangled” her while trying to escape from custody mid-interview, the court heard.
The Romanian national, whose partner and young baby accompanied him to court, had no previous convictions the court heard.
His barrister James Burley said his client, whose family was “supportive”, had been bullied by other inmates while in custody.
Addressing Mustafa Judge Reeds told him: “It’s clear to me that this was not just a spontaneous attack by you. As you got off the bus you must have been looking for someone vulnerable to attack.
“You selected your victim, who was distracted by being on the phone to family and was walking to the underpass. You realised the underpass would be a good place for an attack.
“She must have been terrified - both by the attack and fearing what you might do to her. She thought she was about to be raped by you.
“But she was rescued by passers by and you ran away. Her life was turned upside down by what you did to her.
“This is a particularly serious offence which brings to the fore the need to protect the public and deter others from doing the same. It seems to me not to be a coincidence that both your victims were females.”
Mustafa, of Abbeydale Road, admitted sexual assault and assaulting an emergency worker. He was jailed for three years and told that he would be “eligible” for deportation upon his release.
