United Criminal Alliance-U.C.A. is a breakaway organization from the Criminal Action Force group they have killed a number of IRA people over an extortion racket run by Real IRA.
Late 2010 September was the first time the group did make a public statement when it claimed responsibility for two gun attacks, players lounge shooting and Daniel Gaynor . http://www.herald.ie/news/i-waited-for-gunman-to-finish-me-off-27957797.html over the last 3 years a number of other people have been killed names in next link.
United Criminal Alliance-U.C.A. put out a public statement which said most of the Criminal Action Force members had left the group to set up their own Organization called United Criminal Alliance-U.C.A. they said because a founder member had done something with the Real IRA and he was on his own.
I have a link to an exclusive story in todays Irish Star page 24 on the United Criminal Alliance-U.C.A. the fact that they have not gone away like other poster was thinking.
