A ninja with a headband that had a sun on it was running away from his village. "Come back, you traitor!" Namu, as the villagers called him, effectively defected from The Village hidden in the Land of Light, and ANBU were pursuing him. A shuriken effectively hit his shoulder and he fell into a river.
"We got him, I think," the duck mask ANBU said. They had surrounded him. What you don't know, is that Namu had a special dojutsu which slowed down time. "Ushi, Saru, U, …, Ne, I, Tori" as he finished the hand seals. "His Jutsu speed is unbelievable!" the cat masked one shouted. 'Nope,' Namu smiled in his thoughts. 'Time has just been slowed down for everyone but me.' "Suitong: Suiryudan no Jutsu!" (Water Dragon Bullet Jutsu) A huge dragon manifested out of the river, engulfing all the ANBU.
After taking the shuriken out his shoulder, he ran as fast as he could. The Leaf had to be informed immediately. See, The Village in the Land of Light had a grudge against the Leaf for waging war and decimating the population by the dozens. The Light was preparing to wage war against the Leaf. Namu idealized peace; much like Naruto did, and tried to resolve things by talking it out. When the village heard about his views, they branded him a traitor, chasing him out of the village.
He needed to contact the Leaf authorities. Many lives were at stake here.
