A 71-year-old British woman has been detained in Estepona on a European arrest warrant issued by the UK, where she is charged with a £2.25 million scam. The woman, who police officials described only by her initials, W.R.J., allegedly ran an investment firm between 1993 and 1995 that bilked customers out of anywhere from £500 to £100,000 for bogus investments in rare coins, which were never purchased.
