Mumbai: Actor Rannvijay Singha, who is currently part of the latest season of "MTV Roadies X4", saved a contestant from drowning. As the show enters its pre-finale phase, a task alongside a river will see tensions rise high as one of the contestants named Karishma will experience a near-death experience. During her task, Karishma will be seen fighting for her life as she gets swept under water but Rannvijay will be seen coming to her rescue. A source on the sets said: "It was a dangerous task which required Karishma to cross the river. During her attempt, her float capsized and she fell into the raging waters. It was a scary situation and someone needed to act soon. Without sparing a second, Rannvijay jumped into the cold water and pulled her out." The source added that the currents were so strong that it became difficult for Rannvijay to "maintain his balance". "After a few minutes, he managed to pull her out to safety. It was a close call but Rannvijay just showed the contestants what it takes to be a real Roadie," the source added.
