A suspect believed to be responsible for the deadly New Year’s Eve attack of an Istanbul nightclub has been captured.

Abdulkadir Masharipov is the suspected gunman behind the nightclub massacre that killed 39 people and injured dozens more.

According to an Associated Press report, Masharipov was captured in a police operation Monday afternoon at a home in the Esenyurt district of Istanbul, Turkey. Masharipov’s son was reportedly in the home at the time. The capture followed a two-week manhunt for the perpetrator of the attack, which was executed by the single gunman — but he is believed to have been working in cooperation with the Islamic State. ISIS claimed responsibility for the attack, claiming it was in retaliation for activities of the Turkish military in Northern Syria.

The suspect reportedly shot a police officer and a civilian before storming the nightclub and opening fire on the holiday revelers. He was reportedly wearing a Santa Claus hat at one point during the attack.
