Vic principal resigns after porn claims

A well-respected Victorian principal has resigned after he was photographed allegedly viewing pornography on his office computer.

A photo was taken of Geelong College principal Andrew Barr watching adult pornography at the school before the Easter school holidays, the school says.

It was then distributed on social media site Snapchat.

School council chairman Dr Hugh Seward said on Friday the college acted quickly when the matter was first brought to their attention.

Dr Seward said after a brief investigation, including a check of his computer, Mr Barr resigned.

"The Geelong College council became aware of a matter of concern that might constitute a breach of our standards," Dr Seward said in a statement.

"The Council immediately looked into the matter and when our concerns were confirmed Andrew Barr tendered his resignation."

The college has already started the search for a new principal and say it will be business as normal when students return next week.
