On Saturday, April 12, Britney Salim, 23, was seriously assaulted at her house on Fox Hill Crescent in Sheffield.
Her assailant is believed to have got into her house via the balcony french doors while her nine-month-old daughter Priya was staying with a family friend.
Police are now appealing for information on the whereabouts of Britney’s former partner and Priya’s father, Shaka Williams, who has not been seen since.
Family friend, Katie Bashforth, said: "No one could get in contact with her on the Saturday. When I went in ran upstairs and she was unrecognisable. Her face was black and blue.
"She has seven broken ribs, internal bleeding in her liver, swelling on her brain, a broken jaw, fractures on her face, a collapsed lung and she has had to have a blood transfusion.
“He left her for dead but it feels like the police are leaving finding him up to us. They have kicked a few doors in and that is it.
"We just really want to get it out there because we are really concerned the police are not going to find him any time soon.”
Katie also revealed that Britney came to her house battered and bruised some months ago but decided not to press charges.
She added that Britney's family and friends have been collecting money to go to Priya while her mum is in the hospital.
