Gwent Police have released a man they have been questioning for four days in connection with the suspected murder of a missing 24-year-old.
Kyle Vaughan, known as "Jabbers" and from the Newbridge area, was last seen alive on 30 December.
Detectives were given extra time to question the 27-year-old man arrested last week on suspicion of murder.
They have also released a man, aged 21, and a boy, 15, from Abercarn, held on suspicion of assisting an offender.
A fourth person, a 62-year-old man who was arrested on suspicion of perverting the course of justice, has also previously been given bail.
Mr Vaughan, who has diabetes and needs regular insulin injections, was last seen in the late evening of 30 December in the Abercarn and Risca areas.
Flaming dice tattoo
Later that night his car, a silver Peugeot 306, was found on the A467 between Risca and Crosskeys. Police said it was believed to have been in a collision.
Despite a nationwide appeal, a growing campaign online for information by Mr Vaughan and intense searches by police and family and friends there have been no sightings of the Unilever worker and former Cwmcarn High School pupil.
On Saturday officers visited his family and told them that they now feared that he had died.
Mr Vaughan is 5ft 8in (1.72m), with a slim build, and short dark hair and brown eyes.
He was known to wear a gold neck chain with a cross and has a distinctive tattoo of a pair of flaming dice on his inner left forearm as well as tattoos on his right leg.
Gwent Police asked anyone with information to call 101, 01633 838111 or Crimestoppers on 0800 555111.
