Police in the North have released a man arrested yesterday in connection with the murder of a construction worker in a bomb attack at a British Territorial Army base last week.

The Church of Ireland Bishop of Derry and Raphoe has condemned the murder of 51-year-old David Caldwell by dissident republicans last week.

Rogue republicans were today blamed for a bomb attack which killed a construction worker at a Derry army base.

An explosion, which seriously injured a boy at a Territorial Army centre, in west London, was caused by a torch bomb which had been deliberately planted.
