Deputy assistant police commissioner Neil Basu says that it's a "significant arrest." He said the investigation is ongoing and the terror threat level remains at "critical."
London transport authorities say they have re-opened the station where a bomb partially detonated on a subway car, injuring 29 people.
The blast sent what witnesses described as a fireball through the packed train during the Friday morning rush hour.
The injuries, some from the explosion and others from an ensuing stampede, where not thought to be life-threatening.
British authorities increased the country's terror threat level to "critical", meaning they think another attack may be imminent.
No arrests have been made and a major manhunt for suspects is underway.
Soldiers are being deployed across the country at public sites to assist police.
