The recently reported effect of long-range near-side angular correlations at LHC occurs for large multiplicities of particles with $1,GeV,<p_T,<,3,GeV$. To understand the effect several possibilities have been discussed. In the letter we propose a simple qualitative mechanism which corresponds to gluon bremstralung of quarks moving with acceleration appropriate to the quark--anti-quark string. The smallness of azimuthal angle difference $Delta phi$ along with large $Delta eta$ at large multiplicities in this interval of $p_T$ are natural in the mechanism. The mechanism predicts also bremstralung photons with mean values of $p_T approx 2.9$ and $0.72,GeV$.
