Garda chief Martin Callinan says IRA collusion horrifying

The commissioner of the Irish police, Martin Callinan, has said he is "horrified" that any member of the force would have colluded with the IRA.

It follows judge Peter Smithwick's finding that there was Irish police collusion in the murders of two senior Northern Ireland policemen in 1989.

Mr Callinan spoke to BBC Northern Ireland's Dublin correspondent Shane Harrison.
