A police officer was shot in the hand as he confronted a man suspected of drink driving in south east London.
The Met were called to reports of a car colliding into a number of other vehicles before hitting a lamppost in Westwood Lane, Welling, just after 9pm last night.
Witnesses said the suspected driver was seen to walk off from the scene.
When police officers saw a man matching the description of the driver he is said to have produced a shotgun and pointed it at them.
One of the officers, a male police constable, suffered a gunshot wound to the hand.
A second officer was able to detain the 51-year-old suspect. He was arrested on suspicion of attempted murder and drink driving.
The man remains in custody at a south London police station.
Both officers were taken to hospital and have since been discharged.
A handgun and ammunition were recovered at the scene, the Met said.
Borough Commander of Bexley, Peter Ayling, said: “Last night's incident highlights the dangers that police officers can face as they go about their job.
“My officers, knowing they were faced with a man in possession of a firearm, did not shirk from their duty to protect Londoners.
“They bravely confronted this man, disarmed him and arrested him - I cannot praise their courage enough.”
Officers from Trident are investigating, enquiries continue.
