Humberside Police’s underwater rescue team searched the river this morning and officers walked the banks close to St Andrew’s Quay, now a shopping centre.
The inshore rescue boat Humber Rescue was launched in “horrendous” conditions at 7pm on Sunday, along with the RAF search and rescue helicopter, after a member of the public raised the alarm. They were stood down after two hours.
No one has been reported missing to the police.
A force spokeswoman said: “We won’t be searching unless new information comes in.”
Of last night’s launch, Humber Rescue’s coxswain Dave Roberts said the conditions were among the worst he had seen in the boat’s 25-year history.
