A man armed with a knife has been arrested on suspicion of attempting to murder a police officer.
Metropolitan Police officers used a Taser device on the suspect, in Battersea, south west London, at around 12.30pm today.
The suspect was taken to a south London hospital with minor injuries. A police officer injured in the incident did not require hospital treatment, the Met said.
A force spokesman said: "Police were called to Falcon Road, Battersea, to reports of a man armed with a knife, threatening members of the public.
"Officers attended and the man proceeded to threaten police officers."
Police said the man was apprehended on Este Road, at the junction with Falcon Road, near Clapham Junction rail station.
The spokesman added: "The man has been arrested on suspicion of the attempted murder of a police officer.
"A number of knives were recovered from the scene."
Inquiries are continuing.
Eyewitness Jenilee Graham said she was unaware there was a situation developing until a woman stopped her and told her to get away.
The 23-year-old City worker, from south London, said: "I was coming back from Asda with my mum when we saw a woman who told us to stop where we were going.
"We didn't know what was happening, but then we saw the man who the woman was talking about pop out from behind a bus.
"He ran towards us, then he darted down a side street. It was obviously pretty scary."
She said the suspect was in his mid-20s and was wearing a black jumper, with dark hair and a beard.
