Police given more time to question three men over Olivia's death
Detectives investigating the schoolgirl's murder have been granted an extra 35 hours
Detectives in Liverpool have been granted more time to continue questioning three men being held in connection with the killing of nine-year-old Olivia Pratt-Korbel.
Merseyside Police said they have an extra 36 hours hours to question a 34-year-old man, who was arrested on suspicion of murder and attempted murder, a 41-year-old man and a 29-year-old man, who have both been arrested on suspicion of assisting an offender.
The three were arrested on Sunday (4 September).
Another 34-year-old man, who was the fourth person arrested in the space of 24 hours, is still being interviewed by detectives.
The man, from Liverpool, was arrested on suspicion of assisting an offender after he was stopped by officers on the M42 in the Midlands.
On Monday Merseyside Police urged Twitter users to retweet a post at 10pm calling for people to come forward and share any details they may know about the events surrounding Olivia's death.
It was part of the force's #SilenceIsNotAnOption campaign, and saw more than 850 people retweet the post and more than 1,200 people like it.
Olivia died after she was shot in her home in Dovecot, Liverpool two weeks ago (22 August).
Detective Chief Superintendent and head of investigations Mark Kameen said: "I continue to urge anyone who has information that can help our investigation into Olivia's tragic murder to please come forward so we can bring those responsible to justice.
"A number of people have been arrested in respect of this investigation.
"However, we still need the public's help in ensuring that we can build a strong evidential picture so justice is served for Olivia and her family.
"With this, I appeal for those who may have information, no matter how small, that could continue to help our inquiries, to contact us directly or anonymously and we will do the rest."
