Nigerian authorities have freed four U.S. filmmakers arrested in the Niger Delta region last Saturday.
A statement on the film company's Web site says the Americans and a Nigerian man accompanying them have been released to U.S. embassy personnel in Abuja.
The Seattle-based film company Sweet Crude says Nigerian authorities accused the film crew of traveling in restricted areas. Attorneys for the Americans deny the charges.
Sweet Crude says the filmmakers were making a documentary on oil production in the Delta.
Militants and gangs began attacking oil facilities in the region in 2005 to demand that more oil revenue be directed to impoverished local residents.
