Lancashire Constabulary in the northwest of England has said it is the first in the UK to use such technology to engage with its community, with residents able to use the voice-activated product to get hourly news.
As reported by the Daily Telegraph newspaper, the information available will include images of wanted and missing people, while it will be streamed directly to the app as it's read out.
The project - the brainchild of the force's innovations manager PC Rob Flanagan - will also give users the option of looking at the app to access visual content.
Developers at Amazon have helped realise Flanagan's vision, and he has suggested the idea is ahead of the curve.
He said: "As a police force we are always looking at ways to engage with our communities. Alexa works alongside traditional policing methods to inform the public about the important issues in their neighbourhoods.
"Voice-activated searches now account for 10 per cent of online searches and are expected to rise to 50 per cent by 2020. We want to be at the forefront of this new technology to make it easier for the public to access the information they want to know."
