  For the first time we detected microlensing events at zero latitude in the
Galactic bulge using the VISTA Variables in the Via Lactea Survey (VVV) data.
We have discovered a total sample of N = 630 events within an area covering
20.7 sq. deg. Using the near-IR color magnitude diagram we selected N = 291 red
clump sources, allowing us to analyse the longitude dependence of microlensing
across the central region of the Galactic plane. We thoroughly accounted for
the photometric and sampling efficiency. The spatial distribution is
homogeneous, with the number of events smoothly increasing toward the Galactic
center. We find a slight asymmetry, with a larger number of events toward
negative longitudes than positive longitudes, that is possibly related with the
inclination of the bar along the line of sight. We also examined the timescale
distribution which shows a mean on 17.4 +- 1.0 days for the whole sample, and
20.7 +- 1.0 for the Red Clump subsample.
