Rumours are circulating via WhatsApp and text message of a bomb threat on the London Underground on Monday morning.
However, these claims are entirely false.
A typical message doing the rounds says that police officers are being recalled from leave and told to start work at 4am on Monday after reports of a terror threat against the West End.
To reiterate, these messages are in no way true.
The British Transport Police's Ch Sup Paul Brogden tweeted:
It is thought the rumours spread after the UK terror threat was raised from substantial to severe on Friday.
