Witnesses have reported police activity and an alleged shooting at Greenwood Park Mall in Indiana. However, these reports remain unconfirmed at this time.One witness described seeing police vehicles near the mall entrance and people screaming and running outside. The witness said evacuation announcements were made over the speakers. "What just happened at the mall? We walked in, 2 cop cars were sitting outside with lights on by an entrance, but no officers out there or in the cars. We walked in, got almost to a store & everyone starts screaming & yelling running toward us, & they started speaking over the speakers telling everyone to evacuate the building, so we all just had to run outside and leave as fast as possible. Someone outside running out said there was someone with guns but I'm unsure I just kept going. Anyone know?? Christmas Eve though," the witness wrote in the post. Others also reported police activity on Facebook."I was at target an seen cops flying down Emerson i was wondering what was going on smh first Castleton now Greenwood," another witness wrote. As of now, authorities have not responded to the reports.
