Two 17-year-old boys have died following a stabbing in Milton Keynes last night.
A double murder investigation has been launched this morning, says Thames Valley Police.
Emergency services were called to Emerson Valley just before midnight following reports of a stabbing having taken place.
One of the victims died at the scene, while the other was taken to hospital with serious injuries but later died.
The next of kin of both victims have been informed and are being supported by officers.
No arrests have currently been made.
Two adult males were also injured in the incident and have been taken to hospital with serious, but not life-threatening injuries.
Head of crime, detective chief superintendent Ian Hunter, said: "Thames Valley Police is in the early stages of a double murder investigation after two teenage boys have tragically died in this shocking incident.
"Our priorities at this time are to conduct a thorough investigation and to support those who have been affected. Officers are currently at the scene which has been cordoned off and members of the public are asked to avoid the area.
"I would like to speak to anyone who has any information which could help with our enquiries or anyone who witnessed any suspicious activity in the area of Archford Croft at around the time of the incident around midnight.
"Even if you think details may be insignificant, please come forward and speak to police."
If anyone has information about what has happened, you can contact police via the 24-hour 101 number, quoting URN 1761 19/10.
Or you can call the independent charity Crimestoppers anonymously on 0800 555 111.
