Police investigating the Omagh bombing are hoping a series of newspaper adverts will encourage people to come forward with information on the 1998 attack that killed 29 people.

Chief Superintendent Norman Baxter has urged public representatives to use their influence to encourage people to come forward to the police.

Supt Baxter said that they are particularly interested in the movements of the car used in the attack.

37-year-old south Armagh electrician Sean Hoey has been charged with the killings.

He is awaiting a judge's verdict after standing trial in Belfast.
