Two more teenagers have been arrested in connection with the fatal stabbing of a 21-year-old man in Clacton last weekend.
Harry Burkett, from Grays, suffered a stab wound in Rosemary Road shortly after midnight on Sunday, September 12.
He was treated at the scene by paramedics but died at hospital.
On Wednesday evening, Essex Police arrested a 16-year-old boy on suspicion of murder and a 18-year-old woman on suspicion of assisting an offender.
Both remain in custody at this time.
An 18-year-old man and a 17-year-old girl, who were arrested on suspicion of murder, have been released on bail until October 7.
A 20-year-old woman arrested on suspicion of assisting an offender has also been released on bail until October 7.
Tributes have been paid to Mr Burkett after his death, with his uncle Pete Draper saying: "Words can't even explain how much he will be missed by his family and friends."
Anyone with information that could help officers in their investigation is urged to contact Essex Police, quoting incident number 5 of September 12.
