  We report the synthesis and physical properties studies of quais-1D iron
chalcogenide $\rm BaFe_2Se_4$ which shares the $\rm FeSe_4$ tetrahedra building
motif commonly seen in the iron chalcogenide superconductors. A high-quality
polycrystalline sample was achieved by solid-state reaction method and
characterized by X-ray diffraction, electrical resistivity, magnetic
susceptibility and neutron diffraction measurements. $\rm BaFe_2Se_4$ is a
narrow gap semiconductor that magnetically orders at $\sim$ 310 K. Both neutron
powder diffraction results and isothermal M-H loops suggest a canted
antiferromagnetic structure where Fe sublattice are antiferromagnetically
ordered along the c-axis quasi-1D chain direction, resulting in a net
ferromagnetic moment in the perpendicular direction along the a-axis with
tilted angle of 18.7$^\circ$ towards the b-axis.
