I am trying to select everything after CORP ACT OPTION NO up until 2 new lines and carriage returns (up to safekeeping account in example)

My reg expression atm to extract the info (all of it after CORP ACT OPTION) is 

CORP ACT OPTION NO\.([\s\S]*)

Sample dara:

CORP ACT REFERENCE                  : 007XS0212069115
