Detective Chief Inspector John Caldwell was shot on 22 February in Omagh, where he had been coaching a youth football team.

His young son was with him at the time.

Mr Caldwell spent weeks in a critical but stable condition at Altnagelvin Hospital in Londonderry.

But the Police Service of Northern Ireland said on Thursday that he had been discharged "to continue his recovery".

"We would ask that John and his family are given privacy at this time," they added in a statement.

Mr Caldwell was left with life-changing injuries after the shooting, which police have blamed on the New IRA.

Despite more than a dozen people being arrested in connection with the incident, nobody has been charged with the detective's attempted murder.

Prime Minister Rishi Sunak visited Mr Caldwell in hospital last week and, speaking during a dinner at Hillsborough Castle on Wednesday night, he said: "We sat together and talked about the society he loves and about his ordeal.

"He told me: 'We can't go back'.

"We can't go back.

"If there is one message from the people of Northern Ireland to the world, it is surely this - we will never go back."
