  We continue the investigations of Kirsch, Metzger and the second-named author
[J. Stat. Phys. 143, 1035--1054 (2011)] on spectral properties of a certain
type of random block operators. In particular, we establish an alternative
version of a Wegner estimate and an improved result on Lifschitz tails at the
internal band edges. Using these ingredients and the bootstrap multi-scale
analysis, we also prove dynamical localization in a neighbourhood of the
internal band edges.
