Mumbai Police on Sunday said the reason behind TV actor Tunisha Sharma’s alleged extreme step that ended her life could be her breakup with co-actor Sheezan Khan over a fortnight back. As per the police, the 21-year-old actor who was part of ‘Dabangg 3’ was in a relationship with Sheezan Khan. Early Sunday, the police revealed that Khan has been arrested. He will be presented in court on Monday. The ‘Ali Baba: Dastaan e Kabul’ actor had broken up with the actress 15 days ago. Following the separation, she went into depression. She is said to have been under a lot of stress, according to the police. All these led to her taking the extreme step at a TV soap set in Vasai, the police said, adding though that they are probing the matter from every angle. The First Information Report, or FIR, of the case, revealed that the two actors were in a relationship, and had broken up 15 days ago. Tunisha Sharma was reportedly under stress, and it is suspected that’s what drove her to the edge, said the Mumbai police.
