Capture a STD::unique_loc<std::mutex> in a lambda function which is used as a thread function

Question

Is there any potential problem if capturing a STD::unique_loc<std::mutex> in a lambda function which is used as a thread function? e.g:

int foo()
{
    std::mutex mtxRunOver;
    std::unique_lock <std::mutex> ulkRunOver(mtxRunOver);
    std::thread workThread([&](){
        workThread.detach();
        do_some_process_for_seconds();
        }
    );

    do_some_work();
}
