Inside the bag was a sub-machine gun, a pistol, Taser and some ammunition, according to reports.<\/p>\n
The force said: “At around 21:40 BST a member of the public called police after finding a bag containing Met-issued firearms and a Taser on a street in south London.<\/p>\n
“Within seven minutes of the call to police, officers arrived at the scene and safely recovered the items.<\/p>\n
“We are urgently reviewing the circumstances of this incident and recognise the concern it may cause.”<\/p>\n
Speaking to The Sun, a passerby saw the bag on the side of a road and alerted her partner after becoming suspicious. <\/p>\n
Jordan Griffiths told the newspaper that after looking inside the bag, he took pictures of the contents, then called the police who turned up shortly after.<\/p>\n
“When they arrived they were really shocked. They looked through the bag carefully and hurriedly took them away,” he told the newspaper. <\/p>\n
“I was told they had been left there by one of Sadiq Khan’s security officers, which made sense as he lives here.”<\/p>\n
A spokesperson for Sir Sadiq described the incident as serious, adding: “The Met must now take all steps to ensure an incident like this never occurs again.”<\/p>\n
