Police from the Met’s Counter Terrorism unit are leading an investigation into the suspicious device found on a train at North Greenwich station yesterday.
The Jubilee line was disrupted for a large part of the day after the incident, which began at around 11am, took place.
The item was destroyed by police in a controlled explosion.
“While we are keeping an open mind, the Met’s Counter Terrorism Command is leading the investigation because it has the expertise to deal with incidents of this kind. British Transport Police is supporting them in their investigation,” said a Met spokesperson.
“If anyone saw anything suspicious on this particular train or anywhere else we would urge them to call the Anti-Terrorist Hotline on 0800 789 321, in an emergency always call 999.
“We are asking travellers to check with Transport for London before starting their journey.
“We continue to encourage the public to remain vigilant and alert at all times and report anything suspicious to police,” the spokesperson added.
