Police have arrested a boozed-up teenager who allegedly stole a trolley full of alcohol from a liquor store in Kilsyth in the early hours of Saturday morning.

Police believe the 17-year-old boy broke a window at the Mt Dandenong Road store before raiding the premises, filling a trolley with alcohol and fleeing the scene by foot.

Police said when officers arrived at the store at about 1.40am, they saw smashed glass, a broken window and bottles of alcohol dropped outside the front of the store.

Police patrolled the area and spotted the Kilsyth teenager pushing a trolley along Tennyson Avenue.

They approached the teenager and realised his trolley was full of bottles of alcohol.
