Update (4:35 p.m. ET): The FBI's anchorage field office has denied that it apprehended Shawn Christy, whom Sarah Palin successfully filed a restraining order against last year. This contradicts earlier reports that surfaced following a BBC interview -- shown below -- with Sarah Palin's parents. Christy did visit Alaska last month, but did not run afoul of law enforcement during the trip.
According to the Mat-Su Valley Frontiersman:
Before traveling to Alaska, Christy said he verified with law enforcement and legal authorities in Pennsylvania that his trip to Anchorage would not violate the protective orders.
Earlier: The FBI has reportedly detained Shawn Christy, a 19-year-old man who sent Sarah Palin threatening letters and receipts for a gun he had purchased. An Alaska judge granted Palin a restraining order against Christy last September. According to a report:
[Palin's family has] revealed that Christy was held in Anchorage, just 50 miles from her home in Wasilla. FBI officers have ordered him to return to Pennsylvania, 3,500 miles away.
The BBC interviewed Palin's parents, who spoke about Christy's threats and his apprehension.
