The scene of Monday's attack in Dungannon

The officer was shot a number of times in the arm as he sat in his car at traffic lights in Dungannon on Monday.

He drove back to a nearby police station where he crashed into the front gates. His injuries were not life-threatening.

A man and woman arrested in connection with the incident have both been released without charge.

The shooting happened hours after the Real IRA admitted it shot an off-duty policeman last Thursday in Londonderry.

Detectives are treating both attacks as attempted murder.
