A man has been arrested on suspicion of the murder of a 17-year-old girl who went missing in 1999.
Victoria Hall was on her way home from a nightclub when she vanished 22 years ago.
Her naked body was found in a ditch five days later.
Suffolk Police reopened their investigation into her killing in 2019 after receiving fresh witness information – which they have not expanded upon.
The force said a man was arrested on Wednesday morning on suspicion of murder in connection with the inquiry.
He has been taken into police custody, where he remains for questioning.
The man has not been arrested as part of the inquiry before, officers said. No further details were given about his age or where he was arrested.
Victoria, from Trimley St Mary, went out on the evening of 18 September 1999 with a friend to the Bandbox nightclub in Felixstowe.
The girls left the club at around 1am and parted ways at around 2.20am, yards from Victoria’s home.
That was the last time she was seen alive.
Police launched a missing persons inquiry after her parents discovered she had not returned home.
Victoria’s body was found five days later on 24 September in a ditch by a dog walker in Creeting St Peter, around 25 miles (40km) from where she was last seen.
Her clothing or possessions have never been found.
Detectives continue to ask for anyone with information about Victoria’s death to contact the Major Investigation Team.
