A man has been re-arrested after masked men hijacked a car at gunpoint and ordered the driver to take the vehicle to a Co Tyrone PSNI station.
The 29-year-old was arrested on Wednesday morning.
He was one of two men, a father and son, detained by police earlier this month and later released without charge.

Both men, who are members of Republican Sinn Féin, were detained after three masked men hijacked a car near St Mary's Church in Drumragh, outside Omagh earlier this month.
A suspicious object was placed in the silver-coloured Volkswagen Golf and the driver was told to take the vehicle to Omagh PSNI station where it was abandoned.
The Irish News understands that the 29-year-old had travelled to Strabane with his father on Sunday after he was made aware that his home was being raided.
After dropping off his son, the 56-year-old made his way back to Omagh, where he lives, before he was stopped by police and also detained.
The PSNI say both search and arrest operations were carried out under the Terrorism Act and that two vehicles were seized for forensic examination.
Police later confirmed that following forensic examination, the object was confirmed to be an "elaborate hoax".
The hijacking and security alert comes less than three months after a senior PSNI officer was targeted in Omagh.
Detective Chief Inspector John Caldwell was shot and seriously injured in a New IRA gun attack at a sports complex on the outskirts of the town in February.
In November last year, the driver of a hijacked car was ordered to drive to a police station in Derry after a viable device was placed in his car by members of Arm na Poblachta.
A similar attempt to hijack a vehicle in Derry in February was unsuccessful.
