Uprisings in the Arab world helped Red24, which helps companies deal with security threats such as piracy and kidnap, post a rise in sales and profits in the year to 31 March.Revenue was up to £5.26m from £4.29m the previous year, lifting pre-tax profits to £742,000 from £628,000.Sales were boosted by clients calling up on Red24's services to deal with security problems, with the "Arab Spring" playing an important part in creating demand."We do not budget for these revenues but the world remains an unpredictable place and we envisage that we will continue to get response work of this type," the company said.---RG
