Lucy Letby and Sara Sharif’s killer stepmother ‘are pals and spend hours playing Uno together behind bars’credit: AP Killer nurse Lucy Letby has formed a disturbing friendship with Sara Shariff’s stepmother behind bars, according to reports. Letby, who killed seven babies in her care, and Beinash Batool, 31, serving life for murdering her ten-year-old stepdaughter Sara Sharif, are both locked up in Surrey’s HMP Bronzefield. A prison source told The Sun the unlikely pair have bonded over their love of cheese toasties and the card game Uno – in which players try to get rid of all their cards and yell ‘Uno’ to the annoyance of other prisoners.

They spend ages at the table playing and get really into it. ‘People are angry, but staff have to do what they can to keep prisoners happy.’ They added the child killers both have jobs behind bars with Batool working in the library and Letby starting out as a cleaner. ‘They are also monitored closely by staff as they are at risk of attack. But their lives will stay quite comfortable as long as they behave. ‘The difference between them is that Batool does not discuss her crime, while Letby tells anyone who will listen that’, they alleged. Letby, 35, from Hereford, is serving 15 whole-life orders after she was convicted of murdering seven infants and attempting to murder seven others, with two attempts on one of her victims, between June 2015 and June 2016. Letby, who has always maintained her innocence, lost two bids last year to challenge her convictions at the Court of Appeal for the seven murders and seven attempted murders, and in October for the attempted murder of a baby girl, which she was convicted of by a different jury at a retrial.

Described as a ‘very courageous little girl with an unquenchable spirit’, she suffered years of torture at the hands of dad Urfan, who regularly battered her with a cricket bat, metal pole and phone – even as she lay dying. Sara suffered more than 25 broken bones, iron burns on her bottom, burn marks likely from hot water on her feet, and human adult bite marks during a campaign of abuse spanning at least two years. Her parents fled to Pakistan, leaving Sara’s battered and broken body under the pink duvet on her bunk bed at their Surrey home.
