Abstract. We study spaces obtained from a complete finite volume complex hyperbolic n -manifold M by removing a compact totally geodesic complex (n − 1) -submanifold S . The main result is that the fundamental group of M \ S is relatively hyperbolic, relative to fundamental groups of the ends of M \S , and M \S admits a complete finite volume A -regular Riemannian metric of negative sectional curvature.It follows that for n > 1 the fundamental group of M \ S satisfies Mostow-type Rigidity, has solvable word and conjugacy problems, has finite asymptotic dimension and rapid decay property, satisfies Borel and BaumConnes conjectures, is co-Hopf and residually hyperbolic, has no nontrivial subgroups with property (T), and has finite outer automorphism group. Furthermore, if M is compact, then the fundamental group of M \ S is biautomatic and satisfies Strong Tits Alternative.
