Detective Chief Inspector John Caldwell was shot multiple times in front of young people he had been coaching at a sports centre on 22 February in Co Tyrone.

The so-called New IRA said it carried out the attack, with police looking into whether the group may have been helped by members of a gang.

Last week, 11 people were arrested by the PSNI in the case, with officers also releasing CCTV images.

Those who appeared via video link at Dungannon Magistrates' Court on Monday morning were:

• Jonathan McGinty, 28, of St Julians Downs, Omagh
• Brian Carron, 38, of Claremount Drive, Coalisland
• Gavin Coyle, 45, of Killybrack Mews, Omagh
• Matthew McLean, 33, Glenpark Road, Omagh
• Robert McLean, 29, Deverney Park, Omagh
• James Ivor McLean, 72, of Deverney Park, Omagh
• Alan McFarland, 47, of Deverney Park, Omagh

Carron and Coyle stand further accused of belonging to a proscribed organisation, namely the IRA.

McGinty, McFarland and Matthew McLean are also charged with preparation of terrorist acts.

Coyle, James Ivor McLean and McGinty all had bail applications refused.

All the men spoke to confirm their age, addresses and that they understood the charges against them, apart from Carron, who did not respond.

Mr Caldwell initially spent several weeks in intensive care following the shooting, but was later discharged, and has since made a public appearance at a garden party celebrating a visit to Northern Ireland by the King and Queen.
