A TeV scale leptoquark (LQ) is one of the promising explanations of therecent anomalies in the semileptonic decays of $B$ mesons. Among the variousLQs, the vector $\rm{U}_1$ is capable of explaining the anomalies in both$R_{D^{(*)}}$ and $R_{K^{(*)}}$ observables. We use the current LHC data to putbounds on the parameter space of $\rm{U}_1$ relevant for the anomalies. Precisebounds are drawn by recasting the latest $\tau\tau$ and $\mu\mu$ searches bythe ATLAS and CMS collaborations. We find that it is imperative to include theresonant production modes for obtaining limits in the low mass regions. Forhigher mass points, the non-resonant production modes play a dominant role.
