So, imagine that an extremely dense object, such as a neutron star, is accelerated to close to the speed of light. Its mass increases until it falls inside its Schwarzschild radius and becomes a black hole. However, to an observer flying at the same speed, the object is not a black hole. Say the observer fires some type of absurdly powerful bomb into the object which blows it apart. From a stationary perspective, the explosion would appear from inside the event horizon. Doesn't that kind of go against the whole point of an event horizon? Also, is the object a singularity or not?
