A federal judge in Las Vegas has agreed to let the U.S. Bureau of Land Management resume the roundup of dozens of wild mustangs in northern Nevada but says she remains concerned about critics' complaints the agency is treating the animals inhumanely.
    
U.S District Judge Miranda Du said Thursday she was granting the government's request to lift an emergency injunction that halted the roundup last week because opponents had failed to prove the agency lacked authority to remove the mustangs from the high desert near the Idaho line.
    
The judge said she will issue a formal order on Friday. But she hasn't decided yet if it's necessary to include specific restrictions to ensure the roundup is conducted humanely after BLM wranglers were recently captured on video repeatedly shocking mustangs with electric prods.
