There exists an open 3–manifold M and a simple closed curve γ ⊂ M such that π1(M ∖ γ) is infinitely generated, π1(M) is finitely generated and the preimage of γ in the universal covering of M is equivalent to the standard locally finite set of vertical lines in ℝ3, that is, the trivial link of infinitely many components in ℝ3.
