It remains quite a teary atmosphere here outside the Croydon custody centre on Windmill Road.
A short while ago a dozen uniformed police officers walked silently to the custody centre and laid two large bouquets.
Silently they bowed their heads and left.
A poem pinned to one of the bouquets read:
“Time to come home dear brotherYour tour of duty throughYou have given as much as anyone could be expected to doJust a few steps further the smoke will start to clearOthers here will guide youYou have no need of fearYou have not failed your brothersYou clearly gave it allAnd through your selfless actionsOthers will hear the callSecure your place of honourAmong those who have gone beforeAnd know you will be rememberedFor now and evermore.”

Speaking about what the next steps would be, the Met Police Commissioner Cressida Dick said: “A murder investigation is under way and officers are working at several crime scenes to secure evidence and establish the facts of what happened.
“We are working closely with the Independent Office for Police Conduct.
“Early indications are that the suspect shot himself, this has not yet of course been established as a fact. The man I can tell you remains in a critical condition in hospital.
“I do understand that there is considerable interest in the identity of my colleague. But I cannot tell you yet his name as we have not yet been able to inform all of his close family.
“The investigations will establish the full facts of what has happened and I would ask you as far as is possible to show restraint in speculation at this time.
“This terrible incident underlines again how police officers face danger every single day 24/7-365 in their work to protect our public.
“Thank you all for your thoughts and I will issue more information when I can later today.”

The investigation by the Independent Office for Police Conduct (IOPC) will have several strands.
It's likely to focus on the circumstances of the man's arrest: which officers were deployed during the operation; whether and how the suspect was searched; and if he was put into handcuffs.
The inquiry will need to establish the man's background and if risk assessments were carried out.
It's believed the suspect was known to counter-terrorism police, having been on their radar in the past, though the Met Police has not officially confirmed that.
The IOPC will also need to establish what happened at the police station and whether appropriate measures were put in place when the suspect was taken out of the police van.

The dead officer was shot in the chest before the suspect turned the firearm on himself, the BBC has been told.
The suspect was brought into the custody suite in a police vehicle and the shooting occurred during routine questioning about Covid-19, sources said.
Both men were taken for treatment to St George's Hospital in Tooting, south London, which was guarded by armed police, according to a source.
Lissie Harper, the widow of PC Andrew Harper was killed in the line of duty in August last year, has released a statement about the Croydon officer's death:Quote Message: This is devastating news. No person should go to work never to return. No human being should be stripped of their life in a barbaric act of crime. Another hero has been taken from us in unwarranted violence. They protect us but who protects them? Another life is gone in a disgraceful act that reminds us of the danger our police officers face with every shift they begin. My heart is broken for yet another member of our blue line family, and all of his family, friends and colleagues who must now accept a life without him in it. My thoughts and love are resolutely with them.” from Lissie Harper
Police Insp Richard Berns, who is based with the Met in Camden called the officer "an inspiration to all who knew him".
