Commuters faced delays this morning on the Northern line after a person was taken ill at South Wimbledon underground station.
The incident happened at 9.10am.
The service between Kennington and Morden was hit by delays although a Transport for London spokesperson said a good service was resumed by 9.55am.
On Twitter, Pier Barrett said: "Crowded platform at Colliers Wood, no trains have arrived in 15 mins, no information on screens, no announcement. But still 'good service!'"
