Hi Folks.
The resident experts probably won't find anything new here, but the rest of us might!
http://www.nationalarchives.ie/digital-resources/chief-secretarys-office-crime-branch-dublin-metropolitan-police-dmp-movement-of-extremists-29-may-1915-20-april-1916/report-of-1-june-1915/

It was messing around when I tried it, so some patience may be required to see all docs. I note one is referred to as 2015, I think that should read 1915!

Cheers
