Ali Jayden Maguire (known as AJ) died after being discovered at a Dungannon house with severe injuries.
A 24-year-old woman was arrested by police in Northern Ireland after being accused of the murder of a 2-year-old girl.
She is being held on suspicion of perverting justice, child cruelty, causing or permitting death of a child and causing it to happen.
This is after police had extra time to question another man arrested in connection with the death Ali Jayden Maguire. Maguire died on Friday from head injuries sustained at a Co Tyrone house.
After the child was taken to the hospital, the 32-year old man was taken into police custody by major investigators from the Police Service of Northern Ireland (PSNI).
The PSNI released a statement saying: “Detectives from Police Service of Northern Ireland’s major investigation team investigating circumstances of the death of two-year old girl on Friday, August 6, have been granted a court extension of 36 hours to question a 32 year-old man under suspicion of murder.”
Several tributes were left outside the Park Avenue, Dungannon home where the girl, named AJ, was injured. They included teddy bears and ornaments as well as flowers and cards.
Cuirnan, the aunt of the victim, did not reveal her surname and thanked the public via a Facebook post for their condolences.
Former leader of the DUP and MLA for Fermanagh, South Tyrone Arlene Foster tweeted “Another tragic loss in the constituency, this one a little girl.”
“Thinking about all the people affected by this terrible event and trying to make sense out of it all.”
