Gardai are seeking information on a car with NI license plates after an Irish prison van was rammed in Co Monaghan on Wednesday evening.
The van was rammed by a gold-coloured BMW X5 at around 6.45pm on the N2 Kilcrow in Clontibret.
That car was later found burned out a short distance away, with Garda detectives saying individuals were seen fleeing that scene in a grey/black Audi A4 with NI license plates.
