The case against a man accused of attempting to murder a former RIR soldier has been dropped because of concerns about DNA evidence.
John Hugh Brady, 39, from Lisnafin Park in Strabane, was charged with leaving a bomb under the man's car in 2002.
The former soldier found the device under his car parked in Sion Mills.
The case against Brady was reviewed following a judge's criticism of low copy number DNA evidence during the Omagh bomb trial.
However, Brady remains in prison for the murder of a police officer in 1989.
In 1991 he pleaded guilty to the murder of RUC Reserve Constable David Black, killed after an under-car booby-trap device exploded near his home on the outskirts of Strabane.
Brady was initially released on licence in 1998 after the Good Friday Agreement but his licence was revoked and he was rejailed in November 2003.
In October 2006, Lord Chief Justice Sir Brian Kerr ordered Brady serve a minimum of 15 years of his life sentence before his case can be examined by the Life Sentence review Commissioners.
