DCI John Caldwell still in a critical condition in hospital
A court in Belfast has granted an extension to detain a 33-year-old suspect until 6pm on Sunday, March 5.
An extension was also granted to extend the detention of a 57-year-old man until 10pm on Sunday, March 5.
Both men remain in custody in the Serious Crime Suite at Musgrave Police Station.
Police say the New IRA was behind the attack but were assisted in the planning of the attack by loyalist criminals who provided the guns for the murder.
DCI Caldwell remains in a critical but stable condition in Derry’s Altnagelvin Hospital.
Major Investigation Team detectives continue to ask for the public’s help and would appeal to witnesses or those with information to get in touch by calling 101.
Detectives are also highlighting a reward of up to £20,000 from Crimestoppers, who are a charity and independent of the police.
