A FORMER British aid worker has been arrested in Ethiopia on suspicion of trafficking and sexually abusing orphans, the Foreign Office said on Saturday. David Allen (59) was detained in Addis Ababa after arriving on a flight from Zambia where he was planning to set up a children’s centre. Allen was a former delegate in Ethiopia for the Swiss-based aid agency Terre des Hommes (TDH) but was dismissed in 1996. TDH said it had assisted the authorities in detaining Allen in the Zambian city of Lusaka on August 14. “On the basis of the precise information supplied by Terre des Hommes, the Ethiopian police were able to intercept the suspect during his return flight from Zambia to the UK during a transit at Addis Ababa.” – AFP
