A longtime FBI employee has been hired by the Miami Dolphins to oversee security in the wake of last year's bullying scandal.

Joe Cicini spent 23 years in the Miami division of the FBI, where he worked with the joint terrorism task force and special events task force. He has provided crisis management training to the NFL, MLB, NBA, colleges and universities.

The Dolphins also announced the hiring of Dan Caspersen to oversee the human resources department. Caspersen was executive vice president of human resources for Toys `R' Us from 2006 to 2013, and vice president of human resources for Target from 2001 to 2006.

Brandon Shore, who has worked for the Dolphins in football operations and as finance and legal affairs specialist, will now work in human resources for the team's training facility.

An investigation for the NFL determined that guard Richie Incognito and two other offensive linemen engaged in persistent harassment of tackle Jonathan Martin, another offensive lineman and an assistant trainer last season. Incognito and Martin are no longer with the team.

"We are all committed at this organization to providing a productive and respectful work environment, as well as ensuring the safety and security of all of our employees and fans," Dolphins CEO Tom Garfinkel said in a statement.
