In an abrupt turn of events, WWE has released Alberto Del Rio.  On WWE.com, an official statement was made that simply explains the reason as "due to unprofessional conduct and an altercation with an employee."

Obviously, this story is just breaking and more details will be forthcoming.  They did not cite Del Rio's real name, nor did they wish him the best in his future endeavors.  Given the statement of "unprofessional behavior," maybe they aren't interested in well wishes.

More as it becomes available.
