Surveillance cameras were rolling when an alleged thief stole money from the vending machines at South Windsor High School.
Last November, police say Giuliano was seen on surveillance video using a key to open the vending machines in the school's cafeteria and in the athletic wing and taking the money.
Police say about $600 in bills and coins was taken.
Investigators circulated images from the surveillance cameras. A tip led to Giuliano. He was arrested Wednesday and released on $5,000 bond. He is due in Manchester Superior Court March 17.
