  Direct searches at the Large Hadron Collider (LHC) have pushed the lower
limits on the masses of the gluinos ($\tilde{g}$) and the squarks of the first
two generations ($\tilde{q}$) to the TeV range. On the other hand, the limits
are rather weak for the third generation squarks and masses around a few
hundred GeV are still allowed. A comparatively light third generation of
squarks is also consistent with the lightest Higgs boson with mass $\sim$ 125
GeV. In view of this, we consider the direct production of a pair of sbottom
quarks ($\tilde{b}_1$) at the LHC and study their collider signatures. We focus
on the scenario where the $\tilde{b}_1$ is not the next-to-lightest
supersymmetric particle (NLSP) and hence can also decay to channels other than
the commonly considered decay mode to a bottom quark and the lightest
neutralino ($\tilde{\chi}^0_1$). For example, we consider the decay modes
containing a bottom quark and the second neutralino ($\tilde{b}_1 \to b
\tilde{\chi}^0_2$) and/or a top quark and the lightest chargino ($\tilde{b}_1
\to t \tilde{\chi}^{\pm}_1$) following the leptonic decays of the neutralino,
chargino and the top quark giving rise to a 4 leptons ($\ell$) + 2 $b$-jets +
missing transverse momentum ($\PMET$) final state. We show that an sbottom mass
$\lesssim$ 550 GeV can be probed in this channel at the 14 TeV LHC energy with
integrated luminosity $\lesssim$ 100 fb$^{-1}$.
