Arthashastra
मनुष्य करं वा वृक्षे रक्षो भयं प्ररूपयित्वा सिद्ध व्यञ्जनाः पौर जानपदानां हिरण्येन प्रतिकुर्युः ॥
Or by causing a false panic owing to the arrival of an evil spirit on a tree in the city, wherein a man is hidden making all sorts of devilish noises, the king's spies, under the guise of ascetics, may collect money (with a view to propitiate the evil spirit and send it back).
english translation
