Who has the bat?

How about "John and his brother took a baseball bat to his friend's house."

1 & 2 are the same- have you not typed something in 2? 3 is closest to your meaning, but none of these are good ways of saying this. I'd use something like:
John took his brother, who had a baseball bat, to his troublesome friend's place.
