A man ‘behaving erratically’ was rescued from the river in March after he jumped in yesterday afternoon.
Police, ambulance and three fire engines were called to the scene on Town Bridge just before 4pm.
The man, described as in his early 20s, didn't appear to be in distress and one passerby said he 'had his thumbs up'.
Fire crews confirmed around 5.30pm that the man had been 'brought to safety out of the river'.
He was taken to Peterborough Hospital for further assessment.
Crews from March, Wisbech and Dogsthorpe attended the scene, but no firefighting action was required.
A spokesperson for Cambridgeshire Police said: "We were called at 3.43pm yesterday afternoon (July 31) with reports of concern for a man in March.
"It was reported he was behaving erratically and had entered the river.
"At about 5.30pm the man was out of the water and was detained by ambulance staff under the Mental Health Act."
Traffic in Broad Street was at a standstill while people gathered on the bridge to watch.
