A mother and her young daughter are recovering in hospital from spending 25 minutes in freezing water after plunging 100ft from the Humber Bridge.
The pair were saved by the Humber rescue boat
Bridge staff raised the alarm on Friday night after seeing an empty pram on the footpath near the bridge's south tower.
The woman, who is from Leeds, and the two-year-old girl were pulled from the water by the Humber rescue craft.
The girl is suffering from hypothermia while her mother has various fractures which are not life-threatening.
Ian Bennett from Humber Rescue said the pair were lucky to be alive.
"It's not often we get people in the river for that period of time that have come out. Hopefully they will be OK and recover from this."
Humberside Police, whose helicopter took the mother and daughter from the shore to Hull Royal Infirmary, are investigating the incident.
"Officers are particularly keen to speak to a man who cycled over the bridge not long before the woman left the footpath," a force spokeswoman said.
