A long-standing dispute between two neighboring businesses in the quiet coastal town of Seabrook has taken a disturbing turn. The owner of a local jiu-jitsu studio told police a teenage student was injured by a nail trap allegedly placed by a neighboring doctor. Robert Lee, co-owner and instructor at Cross Collar Jiu-Jitsu, told KHOU 11 that tensions with the neighboring medical office — operated by a colon surgeon — have been simmering for years. But now, he says the conflict is putting people in danger.
