Killer mum Kathryn Smith who stamped her daughter to death has been knifed in prison .

The lifer’s face was slashed in an attack by two inmates in a women’s jail as around 10 lags looked on.

Smith, 23 – caged for the vicious killing of 21-month-old Ayeeshia – is said to have howled in pain as she was punched and stabbed during a four-minute beating in a stairwell not covered by CCTV .

A source said the attack with a home-made knife left Smith with a two-centimetre cut across her cheek.

The incident took place at notorious Foston Hall women’s prison where Magdalena Luczak, who killed four-year-old son Daniel Pelka in Coventry in 2012, hanged herself last year.

It has housed some of Britain’s most evil women, including Moors Murderer Myra Hyndley and Soham liar Maxine Carr.

A source who saw the assault said: “There had been a lot of talk about attacking Smith, but most people wouldn’t go through with it as they don’t want time added on to their sentences.

"But these two really went for it and left her in a bad way.

"No one had any sympathy for Smith. Some staff were saying, ‘What goes around comes around’.”

The attack will raise concerns over security at the Derbyshire jail which houses 300 prisoners.

Drug addict Smith was given a minimum 24 years last month for Ayeeshia’s murder in Burton upon Trent, Staffs.

Her partner, Matthew Rigby, 22, got three and a half years for causing or allowing the tot’s death.

The judge said her life was “brutally snuffed out” by “a vicious beating in her own bedroom”. Her injuries were so severe it looked as though she had been in a car crash.

A prison service official denied a weapon was used in the attack on Smith and said disciplinary action was taken against those involved.
