The history encompassing this idol states that Vighnasur, a demon was created by the King of Gods, Indra to destroy the prayer organized by King Abhinandan. However, the demon went a step further and destroyed all vedic, religious acts and to answer the people's prayers for protection, Ganesh defeated him. The story goes on to say that on being conquered, the demon begged and pleaded with Ganesha to show a mercy. Ganesha then granted in his plea, but on the condition that demon should not go to the place where Ganesha worshipping is going on. In return the demon asked a favour that his name should be taken before Ganesha's name, thus the name of Ganesha became Vighnahar or Vighneshwar (Vighna in Sanskrit means a sudden interruption in the ongoing work due to some unforeseen, unwarranted event or cause). The Ganesha here is called Shri Vighneshwar Vinayak.
