Three teenagers, including a 14-year-old boy, have been arrested on suspicion of murdering a 21-year-old man in a park in Essex.

Emergency services attended Central Park in Chelmsford at about 7pm on Friday, where the victim was found with critical injuries.

Essex police said the 21-year-old died at the scene, despite the efforts of paramedics to save him. An investigation began immediately and quickly led officers to an address in Auckland Close, Chelmsford.

A spokesperson for the force said the suspects, aged 14, 17 and 18, were arrested shortly afterwards and remained in custody for questioning.

The victim’s family have been informed and are receiving support from specially trained officers.

DI Lydia George said: “This is a deeply distressing incident. A family is grieving and our thoughts remain firmly with them at this incredibly difficult time.

“I would call on the public and media to please respect their privacy as we continue the early stages of this investigation. We are determined to get them answers and build as clear a picture as possible of the circumstances surrounding what has happened.”

George added that the police were not looking for any other suspects and that there was no ongoing risk to the public.

“This took place in a busy public area, and while we have already received valuable assistance from the public, we continue to appeal for information. Even the smallest detail could prove crucial.”
