THE police officer blinded by gunman Raoul Moat said tonight his wife had "called time" on their 20-year marriage.

PC David Rathband made the announcement that he and his wife Kath were separating permanently on Twitter.

He Tweeted: "Sad to announce Mrs R has called time on our marriage separation permanent".

Well-wishers swiftly used the micro-blogging site to offer their support and express their sadness.

The officer later Tweeted: "Time to read a book and thanks for all the messages I am fine."

In September, just before the start of the inquest into Moat's death, PC Rathband issued a statement saying he was to live separately from his wife and family.

But that statement stressed the move was "purely for David's rehabilitation and so that he can ultimately continue to support his family."

It said the move had nothing to do with his recent arrest on suspicion of assault and stressed "David and Kath are very much still a married couple who love each other".

PC Rathband was arrested in August after officers were called to an incident at his home in Cramlington, Northumberland.

He was understood to have been released shortly after police arrived.

The 43-year-old was shot twice and blinded on July 4 last year as he sat unarmed in his patrol car.

He has since been hailed for his charity work in the wake of his injuries.

He set up the Blue Lamp Foundation, an organisation offering help to injured members of the emergency services.
