John Paul McGrath at Derry magistrates court last Friday where he faced charges of gathering information about Strabane PSNI Station.
A number of searches were also conducted and the suspect remains in police custody at this time.
Detective Inspector Andrew Hamlin said: “Today’s arrest and searches are linked to the ongoing investigation into an improvised mortar device that was discovered in Church View, Strabane on Saturday, September 7, this year.
“The New IRA were responsible for this reckless attack that put the lives of the local community and local Police officers at risk.
“To date, we have arrested six people and charged a 28 year old man with offences of perverting the course of justice; assisting offenders and recording information of a kind likely to be useful to a person committing or preparing an act of terrorism.”
