Five suspects accused of involvement in the terror attack on Reina nightclub in Istanbul on New Year's Eve were arrested by an Istanbul court on Wednesday.

The suspects named Ali Jameel Mohammed, Aysha Mohammed, Dina Alaa Eid Sayed Ahmed, Eyyüp Korkusuz and Tene Traore, Reina attacker Abdulgadir Masharipov's second wife from an unofficial marriage, were previously detained and taken to court as part of the investigation carried out by Gökalp Kökçü, an Istanbul prosecutor for the terror and organized crime bureau.

The judge on duty decided to arrest the five suspects, who are mostly of foreign nationality, on the charges of "attempting to disrupt constitutional order" and "being a member of an armed terrorist organization", increasing the total number of arrests over the Reina attack to 40.

At least 39 people, including a police officer, were killed when Daesh attacker, Abdulgadir Masharipov, opened fire on partygoers at the Reina nightclub in Istanbul's Ortaköy district early New Year's Day.

Masharipov himself was captured by police in Istanbul after a two-week manhunt last month on the outskirts of the city.
