  The yield of charged particles associated with high-$p_{\rm T}$ trigger
particles ($8 < p_{\rm T} < 15$ GeV/$c$) is measured with the ALICE detector in
Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV relative to proton-proton
collisions at the same energy. The conditional per-trigger yields are extracted
from the narrow jet-like correlation peaks in azimuthal di-hadron correlations.
In the 5% most central collisions, we observe that the yield of associated
charged particles with transverse momenta $p_{\rm T}> 3$ GeV/$c$ on the
away-side drops to about 60% of that observed in pp collisions, while on the
near-side a moderate enhancement of 20-30% is found.
