LINCOLN, Neb. -- A Captain with a southeast Nebraska sheriff's office graduated from the FBI National Academy on Sunday. 

The Lancaster County Sheriff's Office said that Capt. John Vik was one of 237 law enforcement officers who graduated in Quantico, Virginia Dec. 11. 

The 284th session of the National Academy consisted of men and women from 48 states and the District of Columbia.

The Sheriff's Office said the class included members of law enforcement agencies from 25 countries, five military organizations, and five federal civilian organizations.

Internationally known for its academic excellence, the National Academy offers ten weeks of advanced communication, leadership, and fitness training. Participants must have proven records as professionals within their agencies to attend.

On average, these officers have 21 years of law enforcement experience and usually return to their agencies to serve in executive-level positions.
