A man has been arrested after he and a woman were found stabbed in a south London street.
Witnesses reported seeing police with guns and ambulances as the busy Queenstown Road in Battersea was shut after a knife attack tonight.
The Met Police said they were called at just before 6pm to the top of the street, by Battersea Park Road.
Officers said they found a woman with lacerations to her arm and a man who also had cuts to his hand.
Ambulances rushed the woman to hospital as police arrested the man. He is also being taken to hospital for treatment for his injury.
Two cars were also seen to have crashed in an accident at the junction, including a 4x4 which had its windows smashed. Eyewitnesses who were working near to the scene say the woman was stabbed after she abandoned her car, but police have not confirmed these reports.
Witness EJ Ward told the Standard he could see armed officers and six police cars at the junction. The road was cordoned off and police were also seen taping off another area inside the cordon.
Others on social media described "madness" as they saw police with guns and ambulances.
A Met spokeswoman said they are not looking for anyone else in connection with the incident and said: "We believe the two are known to one another."
Transport for London said Queenstown Road has been closed to traffic between Battersea Park Road and Silverthorne Road.
