The following day (Thursday 23 February 2006) Securitas and their insurers offered a reward of £2 million for any information about the heist, which Crimestoppers stated was the largest reward ever offered in the UK. Kent Police said the heist had been meticulously planned by organised crime and that at least £20 million had been stolen, possibly as much as £50 million. By the evening of 23 February 2006, two arrests had been made in Forest Hill, south London. A man aged 29 and a woman aged 31 were detained at separate houses on suspicion of conspiracy to commit robbery. A third person, a 41-year-old woman, was arrested at a branch of the Portman Building Society in Bromley on suspicion of handling stolen goods.
