A 38-year-old man is due in court charged with the attempted murder of a police officer more than six years ago.
He has also been charged with causing an explosion likely to endanger life or cause serious injury to property and membership of a proscribed organisation.
The suspect was arrested on Wednesday and is expected to appear before a sitting of Strabane Magistrates’ Court later.
It is understood the charges are connected to a bomb attack on an off-duty Catholic police officer near Castlederg, Co Tyrone, in 2008.
Dissident republican extremists were blamed for detonating the under-car booby trap device.
The officer was pulled from the mangled wreckage by a member of the public and suffered serious but not life-threatening leg injuries.
Detectives from the Police Service of Northern Ireland’s serious crime branch who are investigating the attack made three arrests on Wednesday.
A 44-year-old man remains in custody while a 37-year-old man was released unconditionally.
A police spokeswoman said the charges could be reviewed by the Public Prosecution Service.
