  Authorities confirmed he escaped from a railway station washroom in New Delhi.
  Det Ch Insp Ceri Hughes said Mr Siddiqi's family "remain resilient and continue to receive our full support".
  Mr Ege is from the Riverside area of Cardiff, but he also has connections with people in surrounding areas.
  DCI Hughes added: "We believe someone in this country knows something about Mohammed Ali Ege's whereabouts, and urge such people to contact us".
