Melbourne youths filmed climbing 14-storey Nylex Clock

The trio were spotted by a 9News helicopter climbing the 14-story building shortly before 5:00pm yesterday.

They were even spotted hanging from the site’s abandoned silos.

The youngsters took a picture of their feet before they got off.

It took about half an hour to go up and down.

After the group returned to the ground, they jumped over the fence and set off on foot.

Police were called to the scene earlier that afternoon just after 2 p.m.

A spokesman confirmed police were called after teenagers were seen climbing a building on Gough Street before returning to the ground at 2.30pm.

Police spoke to three teenagers nearby and gave them directions to move.
