UK police say found 'small bottle' containing Novichok nerve agent

British police said today they have found a "small bottle" containing the Soviet-made nerve agent Novichok in the home of one of two Britons who fell ill from the substance last month.

"On Wednesday, 11 July, a small bottle was recovered during searches of Charlie Rowley's house in Amesbury," police said in a statement, four months after a former Russian spy and his daughter were poisoned with the same substance.

"Scientists have now confirmed to us that the substance contained within the bottle is Novichok.
