TWO ELDERLY women who died when their vehicle was in collision with an unmarked police car last week have been named.

Ann Valley, 87, and Gwyneth DeCamps (formerly Dr Gwyneth Botherway), 88, were travelling in a Nissan Micra when it was in collision with a police dog-unit vehicle on the A4 Bath Road in Calcot at around 3.45pm.

Both women, from Slough, later died from their injuries.

Watchdog, The Independent Office for Police Conduct (IOPC), said it was understood that the Nissan was pulling onto the A4 from Calcot Park Golf Course when the incident happened last Tuesday.

It is carrying out an independent investigation into the actions of the Thames Valley Police officers.

The incident data recorder (IDR), which records the police car’s speed and movements, will be downloaded from the vehicle and analysed as part of the investigation. It has been established the vehicle was travelling with its blue lights activated at the time.

IOPC Regional Director for the south east Sarah Green said: “My thoughts are with all of those affected by this tragic event.

“Our family liaison manager has met the families of Mrs Valley and Mrs DeCamps to offer our condolences and to tell them about our role and our investigation.

“We have placed witness appeal boards in the area and if anyone else can assist us to establish what happened, for the benefit of all of those affected, please make contact with our investigators.”

Witnesses are asked to email calcot@policeconduct.gov.uk or to call  0800 096 9077.
