There has been another arrest in the Garda investigation into the Omagh bombing.
A man in his mid-30s from Dundalk was arrested this morning and is being held in Carrickmacross Garda Station under Section 30 of the Offences Against the State Act.
Three people were detained and questioned in connection with the bombing last Monday. One was released the following day, while the third man was released this morning. None of three were charged.
Over 80 people have been arrested in relation to the inquiry since the bombing, but all but one has been released without charge.
Building contractor Colm Murphy (49) from Ravensdale, Dundalk, Co Louth, was convicted in January by the Special Criminal Court of conspiracy to cause the Omagh bombing and is now serving a 14-year prison sentence.
