  Primordial non-Gaussianity has set strong constraints on models of the early
universe. Studies have shown that Loop Quantum Cosmology (LQC), which is an
attempt to extend inflationary scenario to planck scales, leads to a strongly
scale dependent and oscillatory non-Gaussianity. In particular, the
non-Gaussianity function $f_{_{\rm NL}} (k_1,\, k_2,\, k_3)$ generated in LQC,
though similar to that generated during slow roll inflation at small scales, is
highly scale dependent and oscillatory at long wavelengths. In this work, we
investigate the imprints of such a primordial bispectrum in the bispectrum of
Cosmic Microwave Background (CMB). Inspired by earlier works, we propose an
analytical template for the primordial bispectrum in LQC. We write the template
as a sum of strongly scale dependent and oscillatory part, which captures the
contribution due to the bounce, and a part which captures the scale invariant
behaviour similar to that of slow roll. We then compute the reduced bispectra
of temperature and electric polarisation and their three-point
cross-correlations corresponding to these two parts. We show that the
contribution from the bounce to the reduced bispectrum is negligible compared
to that from the scale-independent part. Thus, we conclude that the CMB
bispectra generated in LQC will be similar to that generated in slow roll
inflation. We conclude with a discussion of our results and its implications to
LQC.
