Blind and visually impaired people will now be able to identify a police officer at their front door safely, thanks to a new security scheme.

Hampshire Constabulary is today launching a new password protocol to protect people.

The Visual Impairment Protocol (VIP) applies to anyone with a visual impairment, whether with full blindness, with a guide dog, or with any sight-impaired condition.

It can also be used by anyone who cares for, or supports, someone who is visually impaired.

A spokesman for Hampshire Constabularysaid it responded to feedback from the community to add an alternative to identity cards, which can be difficult or impossible to read for some of the county's residents.

The issues that led to the introduction of the VIP were first brought to light by Tina Snow, after she experienced a knock on the door from a police officer.

Tina is fully blind, and was not satisfied that the officer could effectively identify himself.

Tina said: “Last year I had a police officer call at my door. He was making enquiries after an attempted break-in at a neighbouring property. Unfortunately he did not have any braille ID on him.

“I let him in, and I shouldn’t have because I was taking a huge risk, as he could have been anybody.

“I contacted Hampshire police and I am really delighted that they have put together a protocol to safeguard people with sight loss in the future.”

In short, the VIP works by setting up a password system at the address of a visually-impaired member of the community. When an individual calls either 101 or 999 and informs the call handler that they have a sight impairment, a password of their choice will be agreed.

When an officer then visits that address, they will be expected to state the password to the person answering the door. If they cannot give the password, then they should not be allowed into the address.

Assistant Chief Constable Craig Dibdin, force lead for disability, said: “When we were contacted by Tina about the circumstances she found herself in, we were quite rightly asked what we can do, or what we already do, to safeguard people in Tina’s position.

“When a police officer knocks on the door of a person with a sight impairment, or severe sight impairment, how does that person satisfy themselves that they are indeed speaking to a police officer?

“We contacted Tina and were absolutely delighted that she was willing to work with us to help us find a solution. Our accessibility team worked with Tina, and as a result of that we developed the Visual Impairment Protocol.

“That protocol is being launched today to coincide with National Inclusion Week and I can’t thank Tina enough for bringing this to our attention and for working with us.

“We have also been working closely with local charities Sight for Wight, Southampton Sight, and Open Sight to gain further feedback from visually impaired members of the community about their experiences with the police, and to introduce this new protocol to them.”

The VIP will be in place across Hampshire and Thames Valley police areas.
