A UK nurse has been arrested for the second time in connection to the unexplained deaths of babies in a neonatal unit.
Police arrested Lucy Letby in connection to the murders of eight babies and the attempted murder of six in July, BBC reports.

The 29-year-old has now been arrested in relation to the attempted murder of an additional three babies.
The Telegraph reports Letby had worked at the Countess of Chester Hospital since 2011.
After she was first arrested, Letby was released on bail as police continued to investigate the deaths.
An independent review was also undertaken at the hospital, due to an apparent rise in sudden deaths.
Police say everything is being done to determine how the babies died.
Det Insp Paul Hughes said the investigation was "challenging" but "very much active and ongoing".
"We fully appreciate that it continues to have a big impact on all those involved," he said in a statement. "Including the families of the babies, staff and patients at the hospital as well as members of the public."
