Police investigating the attempted murder of two police officers in Strabane last November have made three arrests.
Two women, aged 25 and 27, and a 51-year-old man were detained in Strabane, Co Tyrone under the Terrorism Act.
The two officers escaped injury when a roadside bomb was detonated as their vehicle passed by in the Mount Carmel Heights area of the town on 17 November 2022.
They were responding to reports of anti-social behaviour in the area at the time.
Police said as well as the arrests they searched a property and seized some items.
Those detained have been taken to Belfast for questioning.
A man is before the courts charged with two counts of attempted murder in respect of the same incident.
