A homeless man has found confidential blueprints for New York's new Freedom Tower dumped in a city rubbish bin.

Mike Fleming handed the documents - marked "Secure Document - Confidential" in to the New York Post newspaper.

The Freedom Tower is being built at Ground Zero, to replace the World Trade Centre towers destroyed on 9/11.

A spokeswoman apologised for the security breach and said that anyone found responsible would be liable for "serious disciplinary action".
