Two men have been arrested in connection with a double shooting in north London.
Police said it is not a borough that suffers from a lot of gun crime
A man was shot in Upper Street, in Islington, on Wednesday evening and is still critically ill, although stable, police said.
About 30 minutes later, a woman was shot in the back in Finsbury Park Tube station. She is now out of hospital.
Police are questioning a 23-year-old arrested in south-west London and a 19-year-old arrested in north London.
The older man is being held on suspicion of two counts of attempted murder and the younger man for assisting an offender.
Katherine Roberts, eyewitness to the first attack at about 1845 BST, told BBC London: "It was absolutely terrifying.
"I actually crouched down behind a wall because I thought it was the safest place to be."
Chief Supt Barry Norman said: "It's one of the worst things that has happened here in the last three years.
"This is not a borough that suffers a lot of gun crime in spite of us being an inner London borough - so we are all shocked."
