Police have released aerial footage of the arrest of a 36-year-old man on suspicion of murdering nine-year-old Olivia Platt-Korbel.
In the black and white clip, the suspect can be seen being led out of a property and towards a police van, surrounded by marksmen on Thursday evening - a second man was arested on Friday.
Detectives also released an image of a car believed to have taken Joseph Nee - the intended target of the Liverpool shooting - to hospital.
As Olivia lay dying from a gunshot wound to the chest, Nee was picked up by friends in a black Audi Q3 and taken for treatment.
Merseyside Police appealed to anyone who saw the vehicle in the days leading up to the shooting to get in touch.
The vehicle has been seized and is in the process of being forensically examined.
Detective Superintendent Mark Baker said: “Although we have made an arrest in connection with the horrific murder of Olivia, I want to make it completely clear that we need any information about this vehicle or the wider investigation as much as ever.
“Whatever information you have, and whether you are sure that it is the same vehicle or not, pass it on and we will assess its importance.”
Schoolgirl Olivia was shot on Monday night by a gunman who chased convicted drug dealer and burglar Nee, 35, into the family home in Dovecot, also injuring her mother Cheryl, 46.
Police said the 36-year-old man, from the Huyton area, had been arrested on suspicion of Olivia’s murder and two counts of attempted murder after an operation involving armed officers on Thursday night.
On Friday afternoon, a 33-year-old man was detained on the same charges at a property on Lunsford Road, Dovecot.
Both are currently in custody being questioned by detectives.
Armed officers had descended on a block of flats in a raid on Thursday.
One neighbour said: “We saw armed police, all in black with balaclavas on and machine guns.
“They closed the road off.
“They were here at about 10.30pm for about an hour and anyone who came out of their house they would shout at to go in.
“I think it was coming to an end when I saw them becase I saw them putting the battering ram back in the car.”
On Friday afternoon a police Matrix van pulled up in the car park of the flats and five officers were seen entering the top floor flat.
One officer took a ladder in to the property.
Police then left carrying a clear plastic bag which appeared to contain other bags, boxes and material.
Olivia’s family have paid tribute to her, describing her as a “unique, chatty, nosey little girl who broke the mould when she was born”.
They added: “Although her life was short, her personality certainly wasn’t and she lived it to the most she could, and would blow people away with her wit and kindness.”
The family have urged people to “do the right thing”, and said: “If anyone knows anything, now is the time to speak up. It is not about being a ‘snitch’ or a ‘grass’, it is about finding out who took our baby away from us.”
A message on a box of flowers left among tributes at the scene read: “So sorry for your loss of beautiful Olivia. Rest in peace, thinking of all family. Nee family.”
Olivia’s death came 15 years after 11-year-old Rhys Jones was shot dead on his way home from football practice in Croxteth, Liverpool.
On Friday, Home Secretary Priti Patel met police officers and visited the scene where Olivia was shot dead.
Ms Patel has said the Home Office will give Merseyside Police an extra £350,000 to focus on “getting weapons off the streets” and tackling organised crime, and has also launched a £150,000 “care package” for Liverpool residents.
On the flowers from Everton, a message read: “RIP Olivia. No words will lessen the pain or explain such a tragedy.
“Our city stands united.
“Forever in our thoughts.”
A card on the tribute from Liverpool said: “Rest in peace, Olivia, with deepest sympathy from all of us at Liverpool Football Club. ‘You’ll Never Walk Alone’.”
Speaking at a press conference on Friday, Liverpool manager Jurgen Klopp said the shooting was a “tragedy”.
He added: “This is our city. Usually we like to say ‘this is LFC city’ or ‘Everton city’, but in these moments we have to realise it’s our city.
“Whatever we can do together, we have to do it. I don’t like the moments that it happens, but I like the fact that we are then united and support with all we have.”
