Motivated by the recent anomalies in b -> sl(+)l(-) transitions, we explore a minimal Z' scenario, in which the Z' boson has a flavour-changing coupling to charm and top quarks and a flavour-conserving coupling to muons. It is found that such a Z' boson can explain the current b -> sl(+)l(-)anomalies, while satisfying other flavour and collider constraints simultaneously. The Z' boson can be as light as few hundreds GeV. In this case, the t -> c mu(+)mu(-) decay and the tZ' associated production at the LHC could provide sensitive probes of such a Z' boson. As a special feature, the Z' contribu...
