The 6,717 boxes took 11 days to empty, each Safe Deposit premises being turned into a makeshift evidence room as officers, with diamond-tipped drills and angle-grinders, broke into every box. Half were empty, but 3,554 boxes were found to contain, as well as cash and jewellery, stashes of child pornography, false passports, gold, pure cocaine, ivory, firearms, and guns subsequently linked to murders. Operation Rize has been hailed as a great coup. 'The sheer volume of money concerned - £53 million in cash, of which £12.5 million so far has been subsequently seized by the courts,' was the first response from Detective Chief Inspector (now Superintendent) Mark Ponting of Scotland Yard, when asked what he thought made Rize so successful.
So far 250 court appearances have led to 30 convictions, with more in the pipeline. Box 3892 at Edgware Safe Depository, rented in the name of John Derriviere, contained a Brockock hand gun, nine rounds of ammunition, drugs and about £20,000 in cash. Derriviere was convicted of firearms, drugs and money-laundering offences in September 2009 and sentenced to eight years. The box belonging to 49-year-old Yuri Harris, who had previous convictions for stealing lug-gage at Gatwick and Heathrow airports and in Switzerland, contained £101,176.76 made up of sterling, dollars, yen, Swiss francs and Thai baht. As he'd never paid any tax, his cash was taken by the state in lieu.
