Banks could revolutionise the fight against human trafficking and modern slavery by reporting suspicious transactions and other financial activity that ring alarm bells, according to a report on Wednesday. Financial institutions hold data on traffickers and their victims that could play a vital role in combating trafficking - as long as they also collaborate with groups working to stop the trade and supporting survivors, the report said. The report by Royal United Services Institute (RUSI) was launched at an event in London opened by Britain's interior minister, Amber Rudd, who announced 6 million pounds ($7.4 million) of aid money to tackle modern slavery around the world...The panel discussed how the financial sector can shine a light on trafficking networks by flagging suspicious transactions, analysing large amounts of data in new ways and undertaking database investigations. Banks can help police identify and prosecute trafficking cases by providing proof of payments and financial patterns. And on the ground, banks have thousands of staff members who can be trained to look out for possible cases of trafficking. Rob Wainwright, director of Europe's police agency, Europol, said after a slow start, global banks were engaged in fighting trafficking in ways never seen before.
