A WOMAN recovered from the River Weaver was taken to hospital for a 'health assessment' after a late night swim raised serious concerns about her mental condition.

Four fire engines, a rescue boat, police and paramedics were called out late on Sunday evening after reports of a woman sitting on a small island in the middle of the river.

When officers arrived the 49-year-old woman jumped into the river near the Winsford Marina on Station Road, just after 7pm.

Fearing for her safety police called for back up from the fire brigade and ambulance service.

'She was in the river and she kept putting her head under water,' said a Winsford Neighbourhood Policing Unit (NPU) officer.

'At this time we don't know the reasons why. She was taken to Leighton Hospital to be assessed as there were concerns about her mental health.'

Fire crews from Northwich and Winsford were called out, as well as the rescue boat from Warrington and the ambulance service.

Cheshire police spokeswoman, Jacqui Hanson, told the Chronicle the casualty was unable to walk due to coldness in her legs from the icy water.

Winsford police confirmed the woman is known to them, and has 'a history of self-harming', but ruled out the possibility the incident was a failed suicide attempt.
