A specialist underwater search team will be brought in tomorrow as fears grow for the safety of missing Marsden man Jason Webb.
The 40-year-old has been missing since Saturday afternoon, and the last confirmed sighting of him was walking along the Marsden canal towpath at 3pm.
Search teams have been concentrating on the Huddersfield Narrow Canal, the River Colne and Sparth Reservoir, near Marsden.
And the police dedicated underwater search team, which covers Yorkshire and the Humber and is based in Humberside, will be brought in to join the search on Wednesday.
Police have been already been joined by volunteers from the Holme Valley mountain rescue team who have scoured the canal side, riverbanks and surrounding areas between Marsden and Slaithwaite.
There is extra concern due to the very heavy rain across the region over the last few days which has left watercourses at high levels.
Mr Webb was due to watch the England Rugby League side play New Zealand at a pub on Saturday but never arrived. He has not been in touch with his family, which police say is out of character.
He is described as white, 5ft 6ins, slim with short brown hair. A photo released by police shows him with a moustache but he no longer has one.
Since the first appeal, there have been two confirmed sightings of him on Saturday afternoon - one at 1.10pm on Upperhead Row in the town centre near the bus station and the one at Marsden canal tow path.
He appeared to be wearing a two piece olive green waterproof outfit. He was wearing blue jeans and trainers when seen that morning.
Anyone with any information should contact the Kirklees Safeguarding Team via 101 quoting 1648 of 14/11.
