The PC blinded by Raoul Moat has been arrested on suspicion of assault after an incident at a house in Northumberland, say police sources.
Officers were called to PC David Rathband’s address in Cramlington just before midnight following reports of an assault.
The 43-year-old officer, who is married to Kath and has two teenage children, was arrested.
He complained of feeling unwell so was released shortly after pending further inquiries.
A spokeswoman for Northumbria Police said: "Officers attended and a 43-year-old man was arrested on suspicion of assault. Inquiries are ongoing."
Rathband has been praised for his charity work following his injury by gunman Raoul Moat.

Following Moat’s rampage, Rathband, who joined the force in 2000 was blinded in both eyes after the killer shot him at close range.
Moat also shot his ex-girlfriend Samantha Stobbart and killed her new boyfriend before turning a gun on himself when cornered by police.
Last year, Rathband set up the Blue Lamp Foundation to help emergency servicemen and women who had been injured.
A charity spokesman said: "We have no comment to make.
"The family are understandably still coming to terms with the huge impact and changes to their lives as a result of the serious injuries sustained by David whilst on duty and they therefore request that their privacy is respected during this difficult time."
