Man charged over alleged glassing

A man has been charged after allegedly stealing a bike then using a glass to slash open the arm of its owner in southwest Sydney.

Police say the man stole the bicycle from outside a unit block in Liverpool and was wheeling it away in a shopping trolley when he was confronted by the 44-year-old owner at a park in Moorebank late on Thursday night.

Police say the alleged offender then attacked the man with a glass, slicing open his left arm before fleeing the scene.

The injured man was taken to Liverpool Hospital.

His alleged attacker was later arrested and charged with reckless wounding and will face Liverpool Local Court on Friday.
