Juan Vargas, 18, had been asked to leave the Gonzales Supermarket on Collins Street on Friday for undisclosed reasons. At about 5 p.m. though, he returned with a Taser gun and used it on the store's 33-year-old butcher.
There's no indication why he chose to shock the butcher, or if he succeeded.
Currently, no injuries have been reported.
Varges was charged with battery, criminal trespassing and unlawful use of a weapon. Authorities say Vargas also goes by the name Carlos Rios.
