James Watt also known as Tonto (born 21 September 1952) is a former Northern Irish loyalist who was the top bomb maker for the Ulster Volunteer Force (UVF) in the mid-1970s.
In 1978, Watt was convicted and given nine separate life sentences for murder and attempted murder.
These included bombings which killed a ten-year-old boy and two teenagers in two attacks carried out in April 1977 as a part of a UVF bombing campaign against republicans.
Following his release from prison in 1989 he left the organisation and in 1995 became a preacher having embraced Born-again Christianity while serving his sentence.
