British and Colombian authorities have seized nearly £4.4 billion (€6.35 billion) in securities from an international drug and money-laundering ring.
The stocks and bonds were seized in London along with £7 million (€10.1 million) and drugs such as ecstasy and speed, said Colombia's attorney general's office.
Authorities arrested 14 alleged members of the ring - 10 in England, two in Colombia and two in Ecuador.
They also seized cocaine and cannabis allegedly belonging to the gang in Colombia.
The ring allegedly sent drugs from Colombia to Europe via countries like Ecuador and Mexico.
Authorities plan to continue making arrests in other European countries, police said.
The Colombian Navy and the attorney general's office worked with British Customs officials and the National Crime Squad to gather intelligence over the past six months, leading to today's arrests.
