Three men who were arrested in relation to the killing Andrew Burns have been released without charge.
The men were arrested by PSNI in Strabane yesterday morning.
27-year-old Mr Burns, who came from Strabane, was found shot dead last week outside a chapel at Doneyloop, a few miles across the border in Co Donegal.
It is believed he had been abducted after being dropped off by a relative in the centre of Strabane.
