GENEVA — A Swiss newspaper reported Wednesday that a computer specialist for the Panamanian law firm Mossack Fonseca has been taken into custody by Geneva authorities in a probe linked to the leak of a massive trove of data on offshore companies. Daily Le Temps, citing an unidentified person close to the case, reports Geneva prosecutors earlier this week placed the computer specialist for the firm's local office in temporary detention in connection with the recent release of "a very large volume of confidential data.''

The report did not specify when the data was released, but said Geneva prosecutors led a police raid of Mossack Fonseca's local office in which computer equipment was seized.
