A traffic police officer in Weinan, Shaanxi province, was placed in confinement and under investigation after a 65-year-old man was struck by an alleged drunken driver.

Liu Jincun, captain of the urban squadron of the city's Gaoxin brigade, was allegedly driving the car that hit the man about 8:10 pm on June 16.

Passers-by stopped the driver from fleeing, and found that he smelled of alcohol.

The injured man suffered from a concussion and broken bones, according to the doctor who treated him.

"He is in stable condition, but it will take a long time for him to recover," the doctor said.

According to a policeman with the Gaoxin brigade in charge of the case, they had to wait for results of a blood test to see if the officer was drunken driving.
