EMERGENCY call handlers will now instantly know if a member of the public is vulnerable or in potential danger as Police Scotland introduces a new national system to manage 999s.

The system will enable police staff to immediately identify the nearest officer nationwide and tell via the caller’s history if, for example, they are a repeated victim of domestic abuse or suffer health issues.

It will allow the force to know straight away if there have been previous instances of violence associated with a particular number, meaning it can send appropriate resources and gauge the threat to officers.

Police Scotland also said breaking the geographic structures of call handling would assist the force at times of pressure such as Hogmanay or during a major incident when phone lines to one particular area may be jammed.

But the body which represents the overwhelming majority of rank and file officers said an understaffing within police call handling remained.

The system replaces that used by the previous eight regional services, including the troubled Lothian and Borders 999 hub at Bilston Glen where problems led to the M9 tragedy last year.

Lamara Bell, 25, and her boyfriend, John Yuill, 28, lay undiscovered in their car for three days after officers failed to respond to reports of the crash, sparking criticism that the ‘single force’, created just two years before, was failing operationally.

A scathing report on police call-handling published following the deaths in July 2015 included 30 recommendations for Police Scotland.

The call handling system changes were already underway before the probe but the force said it had taken on board recommendations over scrutiny and reassurances when putting the new scheme into practice.

Assistant Chief Constable John Hawkins will update his force’s governing body, the Scottish Police Authority, later this week on the new system, which will bring the call rooms in the east and west of the country together next month.

Writing in today’s Herald, ACC Hawkins said: “We recognise that how we handle calls is a matter of real public interest and that our programme of change has received its fair share of criticism, some of which has been justified.

“The introduction of a national customer relationship management system will allow us, for the first time, to see any previous contact callers have had with us right across Scotland. We will be able to identify any threats or vulnerabilities, for example, where there has been a history of domestic abuse, and prioritise the police response effectively and consistently.”

The force receives over 3.5 million calls from the public every year, the equivalent of one call every nine seconds.

As part of the overall project to modernise its call-handling systems the closure of Police Scotland’s northern control rooms has been delayed until next year, having been expected to shut by the end of 2016.

Calum Steele, general secretary of the Scottish Police Federation, said: “At long last the service is responding to our series of concerns around the vulnerability of call handling. But we still believe there is an understaffing within call handling and the contact centres which needs addressed to give the public a service which is more than a call centre service.”

A Police Scotland spokesman said: “We recognise the critical importance of 999 and 101 for our communities and there will be no change to the way the public contact Police Scotland. They will still call 101 and 999. They will receive the same service delivered by a local officer or a specialist officer if required.”
