Second SA building site arrest

A second teenager has been charged over breaking into Adelaide construction sites and other buildings to film risky behaviour including people hanging off cranes, ledges and walls.

Police will allege five friends broke into several sites over the past four months and posted photos and videos of their activities on the internet.

An 18-year-old man was charged earlier this month with being unlawfully on premises after police seized cameras, memory cards, phones and computers.

A second 18-year-old man has now been charged with the same offence, while an 18-year-old woman and two 17-year-old boys have been cautioned.
