The search for missing Wales rugby fan Ben Thompson, who disappeared after watching the Six Nations' Ireland match, is entering its third week.

Ben Thompson, 34, from Haverfordwest, has not been seen since 2 February, just after he watched the game in the Millennium Stadium.

Specialist sonar equipment will once again be used to search the mouth of the River Ely in Cardiff Bay.

His family continue to be supported by police family liaison officers.

At the end of last week police began detailed searches of a stretch of river between Leckwith Hill bridge and the mouth of the River Ely near Cardiff Bay Yacht Club.

South Wales Police said the search for Mr Thompson will resume there later on Monday.

A big rugby fan, he had travelled to Cardiff for the international match with a friend, staying near Cardiff airport, after winning tickets for a hospitality box in the Millennium Stadium.

He called his wife Jo just after to say he was heading to their favourite pub in the city.

He was seen by friends in Mill Lane in the city centre at about 18:30 GMT and then the last known footage of him captured on CCTV showed him crossing Leckwith Road into Lawrenny Avenue at 19:17 GMT, near Cardiff City stadium.

A few minutes later he was again spotted on camera walking down a lane at the end of that road towards wasteland.

Police say there have been no further sightings of Mr Thompson since and there has been no activity on his mobile phone.
