FRANKFURT (Reuters) - A German insolvency administrator was on Sunday quoted as saying he was considering impounding a second jet used by the Thai Crown Prince, reported German tabloid Bild am Sonntag. "We are considering further steps, including seizing the prince's second plane," the paper quoted insolvency administrator Werner Schneider as saying. German insolvency officials seized a Boeing 737 used by Crown Prince Vajiralongkorn almost two weeks ago to force the Thai government to repay a debt linked to a Bangkok road construction project.
