Chilling new CCTV shows Istanbul nightclub attacker catching bus before massacre as hunt continues for ISIS fanatic
Turkish authorities are still trying to track down the killer after massacre that left 39 revellers dead
TURKISH say they know who carried out the Istanbul New Year's Eve terror shooting - as new footage of the attacker emerged.
Detectives are yet to release his name, but believe the suspect entered Turkey through Syria where he had fought with ISIS.
Turkish Foreign Minister Mevlut Cavusoglu said: "The identity of the person carrying out the attack has been determined."
New CCTV taken last month shows the man walking into a bus terminal in Konya.
He is believed to have then travelled from the city in central Turkey to carry out his murderous rampage that left 39 New Year revellers dead and 70 more injured.
The suspect is believed by police to have travelled to Konya with his wife and two children in November.
Anti-terror chiefs are convinced he had experience of fighting in Syria.
One security source told Reuters that he had "experience in combat for sure. He could have been fighting in Syria for years."
ISIS has already claimed responsibility for the attack.
In a scene of horror, the attacker calmly sprayed some 120 bullets from his AK-47 before disappearing into the night.
He is believed to have used devastating armour-piercing bullets inside the club to cause maximum casualties.
A witness told Turkish newspaper Hurriyet that the gunman had used flash grenades to disorientate victims before picking them off with several magazines of ammunition.
A barman told the newspaper: "The terrorist threw something that lit up every time he finished his magazine. It happened at least three times."
Deputy Prime Minister Numan Kurtulmus said on Monday that the authorities had obtained fingerprint data about the attacker and expressed hope he would be "speedily" identified.
Police arrested 27 people in Izmir this morning, some women and children, as they sought to find their man.
Yesterday it was confirmed a further 14 had been arrested while another two foreign nationals were stopped at Istanbul's main airport.
