Moorgate tube station has been evacuated due to a security alert after a suspicious bag was found on a train.
Pictures uploaded to social media showed at least seven police vehicles surrounding the station amid reports of a bomb scare.
A spokesman for Transport for London told The Independent the evacuation had caused by a bag found on a train.
"Item found at Moorgate station has been looked at by officers and is not suspicious," British Transport Police said in a tweet.
Widespread reports on social media had previously claimed the alert was the result of a bomb scare.
The station has since been reopened.
British Transport Police have been approached for more information.
Last week a suspicious package found on a train at North Greenwich station was destroyed in a controlled explosion.
A 19-year-old man was later arrested on terrorism charges and police said the item was being forensically examined.
“The public will see more officers, including armed police, in and around transport hubs to provide reassurance around public safety,” the Metropolitan Police said in a statement, adding that the Underground was working as normal.
Since August 2014, the terror threat level in Britain has been classed as “severe” – the second highest level, meaning an attack is considered “highly likely”.
