  We construct a family of $q$ deformations of $E(2)$ group for nonzero complex
parameters $|q|<1$ as locally compact braided quantum groups over the circle
group $\mathbb{T}$ viewed as a quasitriangular quantum group with respect to
the unitary R-matrix $R(m,n):=(\zeta)^{mn}$ for all $m,n\in\mathbb{Z}$. For
real $0<|q|<1$, the deformation coincides with Woronowicz's $E_{q}(2)$ groups.
As an application, we study the braided analogue of the contraction procedure
between $SU_{q}(2)$ and $E_{q}(2)$ groups in the spirit of Woronowicz's quantum
analogue of the classic In\"on\"u-Wigner group contraction. Consequently, we
obtain the bosonisation of braided $E_{q}(2)$ groups by contracting $U_{q}(2)$
groups.
