Today police officers are searching in Portobello to try and find Mr Hickin.
Mr Hickin, 42, went missing from Pinderfields Hospital for more than two weeks.
He last seen near Gate 12 of the hospital on Thursday, January 23.
Later that evening he was spotted on the 102 Arriva bus service to Portobello, just after 11pm.
The new images show him wearing a white polo shirt with a dark collar, a light coloured shirt and a waist length hooded black jacket.
He was also wearing grey tracksuit bottoms with a white stripe down the leg and a white emblem on the left leg, and black shoes.
Det Insp Claire Doyles, of Wakefield District CID, said: “The images we are issuing today show Ian on the 102 Portobello bus on the 23rd, and we are now searching in that area for him.
“As time passes we grow more concerned for Ian who is not a well man and we continue to appeal for any information about his welfare and location.
“I would urge anyone who thinks they may have seen Ian or who has information about his whereabouts to contact police.”
