Precision measurements in charm physics offer a window into a unique sector of potential New Physics interactions. LHCb is well equipped to take advantage of the enormous production cross-section of charm mesons in pp collisions at √(s)=7 TeV. The measurement of the D0 -D0 mixing parameters and the search for CP-violation in the charm sector are key physics goals of the LHCb programme. The first CP violation measurements in the charm sector, with 37 pb-1 of data collected in 2010, are discussed. The study of D+ → K- K+ π+ decays shows no indication of CP violation. The measurement of the proper time asymmetry in the time dependent analysis of D0→ K-K+ and D0→ K-K+ is evaluated to be AΓ=(-5.9 ± 5.9stat ± 2.1syst). The difference of CP asymmetry in the time integrated rates of D0→ K-K+ and D0→ π- π+ decays is measured to be (-0.28 ± 0.70stat ± 0.25syst)%.
