A laptop has been seized by police investigating the death of 13-month-old Poppi Worthington in 2012.
The computer is undergoing "meticulous forensic examination" to see whether it is relevant to the case, Cumbria Police said.
Other items have also been recovered, the force added.
It comes months after a man was arrested over a missing laptop used by Poppi's father, Paul Worthington, to watch pornography on the night Poppi was sexually abused and died in December 2012.
A 39-year-old man from Barrow-in-Furness was released under investigation after being held on suspicion of assisting an offender and a drugs offence in March.
:: CPS has no plans to prosecute Poppi Worthington's dad after coroner rules she was abused
Despite Paul Worthington telling police he had watched "adult X-rated" porn on his laptop, officers did not seize the computer at the time.
It was one of a series of errors by Cumbria Police, which lost vital evidence.
No one has been prosecuted over Poppi's sexual abuse and death.
The little girl was taken to hospital after paramedics were called to the Worthington family home in Barrow-in-Furness on the morning of 12 December 2012.
She was pronounced dead shortly after 7am.
:: Poppi Worthington: Post-mortem doctor 'strongly suspected abuse,' inquest hears
An inquest in January found that although she was anally penetrated in her father's double bed, her death did not result from the abuse.
The inquest ruling followed judgments by a High Court family judge in 2014 and 2016 that Poppi was abused by her father shortly before she died.
More from Cumbria
It has previously been ruled that Mr Worthington will not face any legal action and there will be no further review of the case.
Mr Worthington, who denies any wrongdoing, is living in hiding with the help of police protection.
