The gunman who massacred 39 people in an Istanbul nightclub reportedly brought his wife and children with him to Turkey to deflect attention as he prepared his assault.

Three days after the shooting at the Reina club in the early hours of New Year’s Day, Turkish authorities are still hunting for the killer and have yet to publicly identify him.

Sixteen people have been arrested so far in connection with the attack, including two foreigners who were detained at Istanbul’s airport, but the shooter himself remains on the loose.

Among those arrested is a woman identified as the gunman’s wife, who was taken into custody in the city of Konya along with two children.
