PLAINFIELD, Ind. (AP) — Police say a second round of online threats has been made against a suburban Indianapolis mall that was evacuated two days ago.

Plainfield Police Capt. Jared McKee said in a statement that authorities learned of the latest threats to the Shops at Perry Crossing and other Plainfield retailers Sunday evening.

The statement says police are responding to ensure the safety of employees and shoppers and says many businesses plan to remain open until their designated closing time.

On Friday, shoppers at the mall were evacuated after Facebook postings threatened violence there. Authorities said the Facebook postings appeared to have come from the same person who made threats that earlier in the week prompted schools to cancel classes.

The FBI is assisting in an ongoing investigation.
