Brave officers reported that two gunshots were fired at their car, during the pursuit of a suspected stolen vehicle at 3.32am on Tuesday.

The grey Kia Niro Estate was found in the Tulse Hill area and will be recovered for a full forensic examination.
Ch Supt Colin Wingrove, head of policing for Southwark and Lambeth, said: “Such an incident is a prime example of the danger officers put themselves in every day in order to keep Londoners safe.

“I know the public will be shocked to hear of this incident.
“Our specialist detectives are following a number of leads; if you have information that can support them, I ask you to contact us immediately.”
While Supt Dan Ivey, head of neighbourhood policing for Lambeth and Southwark, said: “LambethPolice officers have been shot at trying to intercept a stolen car.
“I know one of the officers well - a brilliantly professional response team cop, a real thief taker - am so proud of him and his operator.”
