Ian Wells, the boyfriend of Maria Hnatiuk, the woman jailed for life last year for the murder of teenage student Rachel Lean, was arrested yesterday. He was last night being questioned in connection with "events leading up to and surrounding" the murder in September 1995. Norfolk police said Mr Wells voluntarily attended North Walsham police station this afternoon with his solicitor and he remained in custody there. Eighteen-year-old Ms Lean (pictured) was found stabbed to death in the woods by an RAF base near her Norfolk home. In November last year, Hnatiuk, 29, was convicted of her murder and jailed for life.
