A 19-year old man has been arrested by counter terrorism police after a suspicious device was blown up in a controlled explosion at North Greenwich Tube station on Thursday.
Officers discharged tasers during the arrest on Holloway Road, north London, but no firearms were discharged. The man has been taken to a London police station, where he remains in custody.
The Met Police said the device had been sent off to be forensically examined.
The device was discovered on an eastbound Jubilee Line train at North Greenwich in south-east London, at about 11:00 BST on Thursday. The tube station was evacuated and members of the Met’s bomb squad carried out the explosion, after the device was described as looking “real enough”.
Rail union bosses had earlier called for a security summit after the suspect device was found.
