Chennai, Aug 17 (IANS) Actor-politician Nandamuri Balakrishna, known for his temper, has again slapped a fan -- for getting too close for a selfie. The incident happened on Wednesday night when he was in Nandyal in Andhra Pradesh to campaign for the ruling Telugu Desam Party in a byelection. According to a video on Twitter, Balakrishna, 57, is seen slapping a fan for trying to get too close for a picture. He then stares at him and walks away angrily. The video clip has gone viral on social media. This is not the first time Balakrishna has found himself in such a situation. Last year, during a visit to the Tirumala temple, he had slapped someone who tried to take a selfie with him. Earlier this month, on the sets of his upcoming yet-untitled Telugu film with K.S Ravi Kumar, a leaked video showed an angry Balakrishna slapping his assistant and ordering him to tie his shoe laces. Balakrishna's upcoming Telugu action entertainer "Paisa Vasool" is slated for a September 1 release.
