Two men arrested in connection to the attempted murder of Detective Chief Inspector John Caldwell in Omagh will remain in custody for further questioning, a judge has ruled. 

The Belfast court gave PSNI permission to detain a 33-year-old suspect until 6pm on Sunday and a 57-year-old man until 10pm on Sunday.

Six men previously arrested have been released. 

The charity Crimestoppers is offered a reward of £20,000 for information that leads to the conviction of those involved.
