HOUSTON — A Houston man has been arrested after he was allegedly caught trying to plant explosives on a Confederate statue at a Houston park, authorities said Monday. Prosecutors allege 25-year-old Andrew Schneck was caught on Saturday evening near a statue of Richard Dowling, a lieutenant in the Confederate army. A Houston park ranger found Schneck holding two boxes with duct tape and wires as well as a bottle and a small tube containing compounds that tests later revealed were explosive materials, according to a criminal complaint.
