A busy London Underground station temporarily closed for almost an hour because it did not have enough staff.
Travellers who wanted to use Oxford Circus underground, in the heart of central London's busy shopping district, found it was shut from 8.58am to 9.46am, and that trains were not stopping.
Oxford Circus is a connecting hub for the Bakerloo, Central and Victoria lines.
A Transport for London spokesman said: "Due to a staff shortage, Oxford Circus Underground Station was closed for a short period between 8.58am and 9.46am with trains not stopping at the station. This has now been resolved and all trains are stopping normally.
"During the short station closures, customers could continue to use Tube stations in the area, including Bond Street, Piccadilly Circus and Tottenham Court Road."
Passengers were evacuated from the station as an emergency alarm sounded.
A repeated announcement said: "Ladies and gentlemen, your attention please: due to a reported emergency would all passengers leave the station immediately."
A sign reading "Emergency do not enter" was illuminated over the entrances to the station before the gates were closed.
