Tortious Interference in Business Deal

Rahul, Managing Director of XYZ Electronics, met with potential investor, Mr. Kumar, at a hotel coffee shop. Unbeknownst to Rahul, a business rival, Vikas, was also present and overheard the discussion. Vikas immediately called a friend who was a director in Rahul's company and falsely informed him that Rahul had agreed to sell his company's shares to Mr. Kumar at a significantly lower price than the actual market value. The director, believing the false information, proceeded to buy up all the available shares, thus acquiring a controlling stake in the company. The company's losses are now substantial.

What tort remedy would be available to Rahul against Vikas for his actions?
