The current experimental limit on Charge Lepton Flavour
Violating (CLFV) processes allows the branching ratios of $h \to \tau
\mu$ and $h \to \tau e$ processes to be of order 10%. Since such CLFV
processes are forbidden in the Standard Model (SM), we aim to explain
these processes by employing the Froggatt-Nielsen mechanism. This
mechanism requires the addition of a scalar field called the flavon,
singlet under SM gauge group which breaks spontaneously due to the
flavon field acquiring a Vacuum Expectation Value (VEV). We show that
the observed CLFV branching ratios can be explained due to the flavon
filed mixing with the Higgs boson passing all experimental bounds.
