A second man has been arrested on suspicion of being involved in the murder of Suffolk teenager, Luke Durbin.
The 19-year-old disappeared in 2006 after a night out in Ipswich. It is still not known what happened to him.
A 25-year-old man was detained yesterday evening and was taken to the Martlesham Police Investigation Centre for questioning.
A 40-year-old man arrested earlier in the day remains in custody.
Properties within the county remain cordoned off as inquiries continue.
