Jack Smith has known Daniel Gliksten for nearly 14 years. They went to school together in Suffolk and Jack remains friends with Daniel and his family, despite Daniel's various moves within England and eventually overseas.
Jack says his group of friends are all very outgoing and clever and they were supportive of Daniel's decision to study in Hungary. He describes Daniel as 'the best of a bright lot'.
Jack found out about Daniel's disappearance when he saw a report on ITV Anglia. He says the news shocked him and that it would be totally out of character for this experienced traveller to go off somewhere without getting in touch.
