Emergency services were called to Regency Court where they found three people who had been injured at around 1.30am today.
Despite the efforts of medics, two of those people have now died. Their families are being supported by specialist officers.
The third victim was treated for injuries that are not life-threatening or life-changing.
Detectives are working to establish how the boys died and a post-mortem examination will be carried out.
“This incident has required an immediate and a large-scale response and officers and investigators have worked through the night to piece together what happened in the lead up to this tragic incident,” said Detective Chief Inspector Andy Clarkson.
“We understand there will naturally be shock and concern within the community after such a tragic loss of life. But, at this stage, we do not believe there is any wider threat to the public.
“We know there were a number of witnesses to this incident and I would urge anyone who saw anything in Regency Court and the roads around it in central Brentwood between 1am and 2am to come forward and speak to us if you have not already done so.”
Chief Inspector Mark Barber added: “There will continue to be a highly visible police presence in Brentwood this morning and indeed throughout the day.
“I am acutely aware that this incident will shock many without the community. My officers will be there throughout the day – they will be there to reassure you and keep you safe. If you have any concerns or information on the incident then, please, do not hesitate to come forward and speak to them.”
Anyone who witnessed the incident or who has information should contact Essex Police by calling 101 and citing incident 125 of Sunday, 24 October.
