One of two brawling Woodbury brothers was charged with assault after a mousetrap prank led to a fight, a bloody lip and an arrest, the Woodbury Bulletin reported.

Police charged 23-year-old Matthew Joseph Nelson last week with one count of third-degree assault and one count of domestic assault after his 27-year-old brother set a mousetrap to go off when Nelson entered his room, the publication reported. That led to fisticuffs, and Nelson's brother had four stitches to close a gash in his lip, the Bulletin reported.

Nelson was released on bail and due in court Feb. 20.
