A murder investigation is underway in Essex after a man was stabbed to death with three others suffering "life threatening" injuries in a late-night brawl.

Essex Police confirmed that a man in his 20s had been stabbed in the chest in the Grays area after they were called to reports of a fighting at around 12.35am on Saturday 1 July.

The man died at the scene after paramedics tried to save him. Three others were taken to Basildon Hospital suffering from "life threatening injuries."

One was an 18-year-old man from Tilbury, who suffered a chest wound, another 18-year-old man from Tilbury suffered a serious stomach wound, and a 39-year-old man from the Corringham area suffered a stomach wound.
