Chengdu auxiliary police jumped into the river while performing their duties, and their whereabouts are still unknown. What happened?

According to Chengdu Daily, on March 22nd 13: 30, two traffic policemen from the Sixth Squadron of Shuangliu Branch of Chengdu Public Security Bureau led seven auxiliary police officers to set up checkpoints at the intersection of Yong 'an Bridge and Xinjie Community in Yong 'an Town. A white Chevrolet sedan with the license plate of Sichuan AM68J9 turned around and fled at a distance of more than 0 meter from the card point/kloc-0. Sun Zhe and two other auxiliary police officers stepped forward to intercept him. After getting off the bus and punching Sun Zhe, the driver of the car fled to Yongtai Road on the lower bank of Yong 'an Bridge and suddenly jumped into the river.

Wan Yu, an auxiliary police officer, and others immediately jumped into the river to rescue the driver. Later, due to the rapidity of the river, Wan Yu was exhausted and sank into the water. The driver swam across the river and ran away. On March 22nd, from afternoon till late at night, many people were worried about the whereabouts of an auxiliary police officer. During the mission, Wan Yu jumped into the river and was never seen again.

At present, Shuangliu Public Security has mobilized many police types such as firefighting to actively carry out search and rescue. The local government has organized comprehensive management forces and the masses to actively participate in the rescue, but no trace of more than 10,000 people has been found, and the search and rescue work is still in progress.
