Partial answer looking for more

Although I found it highly unlikely that Gandhi would do that given his philosophy of Satyagraha -- non-violent resistence -- I did a search to find any hint of his violence toward his foes. There are many thorough biographies of Mohandas Gandhi both online and in book form (Mahatma is an honorific). I found plenty of information writing about Gandhi's non-violent theories, political actions and way of life, but couldn't find any information to support your question.

Please let me know if you'd like me to search more. I'd be happy to look through some books on Gandhi available in a university library near me.
