The father of murdered policewoman Sharon Beshenivsky has visited the spot in Bradford where his daughter was gunned down by armed robbers.
Pc Beshenivsky's father Billy Jagger visits the scene of the shooting
The 38-year-old was shot dead and her colleague Pc Teresa Milburn, 37, injured during the raid at a travel agency in Morley Street on Friday.
Her tearful father, Billy Jagger, laid flowers among a growing swathe of floral tributes to the shot officer.
Six people are still being questioned in West Yorkshire over the shootings.
The five men - all Somalians - and a woman, whose nationality is not known, were arrested in London over the weekend and brought to police stations in West Yorkshire.
Streets around the scene of the robbery remained cordoned off on Monday as forensic examinations continued.
Pc Beshenivsky had three children and two step-children
Pc Beshenivsky's aunt Nora Stead described her niece's death as "heartbreaking".
"I know she was doing what she wanted to do, she told me it was what she wanted to do," she said.
"I just hope some good comes out of this. I just hope justice is done."
On Monday, Pc Beshenivsky's boss, divisional commander Ch Supt Sarah Brown, described her death as the "worst nightmare" for a police chief.
Opening a book of condolence at Bradford's City Hall, Ms Brown said Pc Beshenivsky's death was a massive tragedy for the whole force.
"The mood at the station continues to be one of sombre determination as we all try to come to terms with what has happened.
"We have lost one of our colleagues and another has been seriously injured in the most dreadful of circumstances.
"We have taken some comfort from the messages of condolence we are receiving from throughout the world."
Pc Milburn, who was shot in the shoulder by the robbers, paid tribute to her dead colleague, after leaving hospital in a wheelchair.
She said: "Friday should have been a normal day at work, instead I lost a colleague and a dear friend.
"Sharon and I enjoyed working together immensely.
"Nothing can bring Sharon back and my wholehearted sympathy goes out to her family.
"Despite my own injuries I am thankful to be back at home with my family."
Travel agency owners in Bradford said the robbery was one of a growing number of raids on Pakistani-owned businesses.
Significant amounts of cash are handed in at travel agencies by people arranging money transfers for relatives in Pakistan.
Shahid Bhatti, owner of Bradford Travel on Lumb Lane in Bradford city centre, said: "Over the past 10 years a pattern has been established of robberies on travel agencies in Bradford.
"We have been targeted because people know about the money transfers.
"My brother was robbed outside our office in 1997 and since then we have increased our security. We have installed CCTV cameras and we report any unusual behaviour on Lumb Lane.
"This incident is a horrible tragedy, but we've been expecting something like this."
