Target made waves after announcing that shoppers are free to use the bathroom in which they feel most comfortable, based on their gender identity, following North Carolina’s hotly-contested bathroom bill.
"Transgender team members and guests to use the restroom or fitting room facility that corresponds with their gender identity,” Target stated.
There has not been a determination made whether the bomb was directly related to the bathroom backlash.
On Thursday, a 44-year-old woman was taken into custody, but no charges have yet been filed.
"The detectives are not currently looking for any known additional suspects, and (at) this point there is no indication that the incident is related to any policies that the Target store has in place," a statement issued by the police reads.
