Federal authorities arrested 23-year-old Oscar Hernandez Jr. on Wednesday evening in Florida on charges of obstruction of justice, witness tampering and lying to a federal grand jury. The case is "related" to the athlete's case, the U.S. attorney's office in Boston said.
The men themselves are not related.
Oscar Hernandez is accused of lying to a grand jury investigating the transportation of guns from Florida to Massachusetts. The inquiry was focused on three guns recovered in connection with the 2013 killing of semi-pro football player and Aaron Hernandez associate Odin Lloyd.
Aaron Hernandez and two other men are charged in the June 17 shooting death of Lloyd, who was found dead about a mile from Hernandez's North Attleborough home.
Oscar Hernandez appeared in U.S. District Court in Orlando, Fla. on Thursday. He is scheduled to be brought to Massachusetts later to face charges.
