Detectives from the PSNI's Terrorism Investigation Unit arrested a 28-year-old man in the Strabane area of Co Tyrone on Wednesday in connection with what was described at the time by chief constable Simon Byrne as a "callous attempt to kill or maim" police officers.
A number of searches also are continuing in the area.
Detective Inspector Andrew Hamlin from the unit said the arrest and searches were linked to an ongoing investigation into a mortar device that was discovered in Church View, Strabane on Saturday September 7th.
“Whilst the device was aimed at the nearby police station and was undoubtedly designed to injure or murder police officers who work to keep local people safe, it was recklessly left in a public area, just metres away from a number of family homes,” he said.
“The New IRA were behind the attack and they demonstrated once again that they do not care who is hurt or killed by their violent actions,” added Detective Inspector Hamlin.
“A number of small children were in close proximity to the deadly device and it is disgraceful that their lives were put at risk. A number of older and vulnerable people were also forced to leave the comfort and safety of their own homes,” he said.
Detective Inspector Hamlin added, “I believe that the New IRA members behind this attack are living in the community, amongst the people whose lives they put at risk. Our focus is on keeping the community safe and protecting them from the threat posed by these violent groups but we need the help of the public.
“Our chances of success are vastly improved by support and information from community as today’s search and arrest operation demonstrates. I would strongly urge people to report any suspicions they have about dangerous and illegal activity in our community to police.”
