The latest CCTV footage, obtained by Turkish broadcaster Haberturk, was taken from a camera near elevators at the airport moments before the main attack got underway.
"Three suicide bombers went on a coordinated rampage through the terminal on Tuesday night killing 43 people - 19 of them foreigners - and injuring more than 300."
The officer is believed to have approached the bomber because he was suspicious about him wearing a raincoat in summer.
They exchange words before footage shows the policeman rolling around on the floor.
After seeing that the officer was not dead, the gunman reportedly extended his arm and shot at his victim again.
The three smiling suicide bombers are seen walking calmly together towards the airport, wearing heavy clothes with one carrying a bag
According to the Mirror, the condition of the policeman is not yet known.
