We study the parameterized complexity of the Bounded-Degree Vertex Deletion problem (BDD),

where the aim is to find a maximum induced subgraph whose maximum degree is below a given

degree bound. Our focus lies on parameters that measure the structural properties of the input

instance. We first show that the problem is W[1]-hard parameterized by a wide range of fairly

restrictive structural parameters such as the feedback vertex set number, pathwidth, treedepth,

and even the size of a minimum vertex deletion set into graphs of pathwidth and treedepth at

most three. We thereby resolve the main open question stated in Betzler, Bredereck, Niedermeier

and Uhlmann (2012) concerning the complexity of BDD parameterized by the feedback vertex

set number. On the positive side, we obtain fixed-parameter algorithms for the problem with

respect to the decompositional parameter treecut width and a novel problem-specific parameter

called the core fracture number.
