A 20-year-old woman was rescued from being stuck in the mud by Stoke Bridge, Ipswich in the early hours.
A passer-by called the ambulance service at around 3.30am and paramedics requested help from police and fire crews.
A Suffolk police spokesman said the woman had a friend with her who had unsuccessfully attempted to help the victim out of the mud.
He added: “The female was able to get out by 3.50am and she was seen by paramedics and taken to Ipswich Hospital.”
A spokesman from The East of England Ambulance Service NHS Trust said he believed the woman suffered injuries to the side of her body which were not life-threatening or serious.
Two fire engines, one from Ipswich East and one from Princes Street, as well as an ambulance crew, ambulance officer and the hazardous area response team, attended the accident.
