Mebo Telecommunications AG (formed in 1969 and registered in Zürich on 24 March 1971) is owned by Swiss businessmen Erwin Meister and Edwin Bollier. Radio Nordsee International – the Mebo I and II Mebo bought two vessels in 1969: Mebo I and the 630 ton Mebo II (formerly "Silvretta"). The latter was fitted out as an offshore radio ship and broadcast as Radio Nordsee International between 1970 and 1974, off the coast of Scheveningen and, for a few months, Essex. The smaller Mebo I was used as a supply tender, and was renamed Angela (after Mrs Meister). When the Netherlands outlawed the supply of offshore radio broadcasters, and after a legal battle with the Dutch government over the impounding of the Mebo II, Mebo leased (later, sold) the Angela and Mebo II to Libya in 1977. Mebo II was renamed El Fatah and broadcast Libyan radio programmes from Tripoli harbour. In 1984, both El Fatah and Almasira (ex Angela) were used as target practice by the Libyan navy and airforce, and were sunk in the Gulf of Sidra. Lockerbie trial Because a Mebo Telecommunications timing device was alleged to have been used to trigger the bomb that destroyed Pan Am Flight 103 over Lockerbie on 21 December 1988 killing 270 people, Erwin Meister and Edwin Bollier were summoned to give evidence in the second month of the Lockerbie trial. Timers for Libya In week 7 of the trial, Meister testified that Mebo had supplied Libya with 20 MST-13 timing devices, and identified one of the two accused (Abdelbaset al-Megrahi) as a former business contact. The defence asked Meister, under cross-examination, to explain the purpose of his visit to Syria in 1984. Meister's partner, Edwin Bollier, was questioned in week 8. Bollier said Mebo made a range of products including briefcases equipped to radio-detonate IEDs. He agreed that Mebo had sold 20 MST-13 timers to Libya in 1985, which were later tested by Libyan special forces at their base at Sabha. Bollier said: "I was present when two such timers were included in bomb cylinders". In court, Bollier was shown a number of printed circuit board fragments which he identified as coming from the Mebo MST-13 timer, but he claimed that these timer fragments appeared to have been modified. Timers for East Germany Joachim Wenzel, an employee of the Stasi, the former East German intelligence agency, testified behind screens in week
