"New information is coming in all the time and this continues to be a fast-moving enquiry.

"Our enquiries continue to learn more about his roots and his links within the UK and overseas.

"We still need anyone who knows him, who may have spent time with him over the last few weeks or before this to get in touch and tell us more about his background so that we can trace his movements."
