Almost a dozen people died during or following contact with Surrey Police in the past five year, new figures show.

It come as a recent report from the Independent Office for Police Conduct found a significant number of deaths involving police in England and Wales relate to mental health, drugs, and alcohol.

According to the report, there were 186 deaths involving police across the two nations in the year to March – down slightly from 199 the year before.

Over the past five years there have been 11 deaths involving Surrey Police, but none were recorded last year.

Of the deaths involving the police force in recent years, one was a road traffic incident. Another five were apparent suicides after custody.

The IOPC also investigated five deaths which were due to a range of other possible circumstances after contact with the force.

The figures also showed the number of deaths during or after police custody nationally hit a record high, with 24 fatalities last year. The IOPC said 19 of the people who died during or after custody had "mental health concerns".

Deborah Coles, director of the charity Inquest, said: "No one should be dying at the hands of police. Yet every year, more people are dying in and following police custody."

She added: "The fact that the majority of these deaths relate to mental ill health and drugs and alcohol reiterates the urgent need for a community health and not a policing response.

"Ultimately to prevent further deaths and harm, we must look beyond policing and redirect resources into community, health, welfare and specialist drug and alcohol services."

IOPC director general Rachel Watson said: "Past figures show mental ill health to be a consistent factor among those who die in or following custody, but it features even more starkly this year.

"Furthermore, in 48 of the 68 apparent suicides, and in just under half of the 60 other deaths we investigated, mental health was identified as a relevant factor."

While not all deaths where police have been in contact with someone will be preventable, she said it was "disappointing" to see increases this year among deaths in or following custody, road traffic fatalities and post-custody apparent suicides.

She added: "It is important that any learning from investigations is acted on and fed into improvements to help police officers better manage risk."

Ivan Balhatchet, National Police Chiefs' Council’s lead on custody and acting chief constable for Northamptonshire Polices, said police custody "plays a pivotal role in keeping the public safe and supporting the criminal justice process".

He added it is a challenging and high-risk environment in which staff "care for some of the most vulnerable and challenging people in society".

"We are acutely aware of the huge responsibility policing has to protect the physical and mental welfare of the people we come into contact with," he said.

"It is right that every death is independently scrutinised and fully investigated to ensure that any learning is taken forward and acted upon."
