Officers received calls at 8.20pm with concerns for a man sitting on the Sawtry flyover threatening to jump off. A spokesman for Cambridgeshire police said: About 10 minutes later he did fall from the flyover and was killed. We are not treating the death as suspicious and the file has been passed to the coroner. He added the man was 39-years-old. The road was completely shut between junctions 15 and 16 but the southbound carriageway opened not long after the incident. The northbound carriageway was shut until about 2am.
