Jokers drew a huge willy on the roof of a school that was so large it could be spotted from space.

However, the willy wasn't noticed until it was seen on Google Earth.

It is thought former pupils at Yarm School at Stockton on Tees carried out the prank.

According to the Sun one former pupil said: "A couple of ex-students hopped over the school fence on a weekend and went unnoticed by guards.

"They managed to get on the roof of the Friary building and somehow mark on the willy. They also burnt a manhood into the grass."

Although the willy on the roof has been removed the outline can still be seen on Google.
