(La Porte, IN) - What caused a lengthy power outage at Walmart in La Porte is not known.  Customers were asked to leave the building Wednesday about 9 a.m.  The store at E. Lincolnway and Boyd Boulevard reopened just before 11 a.m.

NIPSCO spokesperson Katie Dorsey said two other nearby businesses also lost power during that time period. 

Dorsey said crews looked for the source of the outage but were not able to come up with the cause.  “They weren’t able to identify anything in particular that was wrong with the system,” she said.
