PRANKSTERS could have jeopardised the rescue of a woman from the River Great Ouse by shining a laser light at a police helicopter.

The 34-year-old was fished out of the water by firefighters wearing dry suits after plunging in near the Flood Tavern in St Ives on Friday at 9.55pm.

Ppolice officers had to speak to three teens after a laser light was aimed at a Cambridgeshire Police helicopter also called to attend.

A police spokesman said: "A 15-year-old boy and two girls, aged 14 and 16, were located nearby and spoken to by officers. Investigations are ongoing."

One fire crew from St Ives, one crew from Huntingdon and a rescue vehicle from Huntingdon were called to the scene near the Flood Tavern in St Ives.

The woman was given assistance by paramedics, and taken to Hinchingbrooke Hospital, but later arrested on suspicion of assault and breaching a court order. She has been bailed until August 2.
