Philadelphia police are investigating an alleged plot to attack the Pennsylvania Convention Center in Philadelphia on Thursday night.

Action News has learned that police got a tip about a group driving up from Virginia in a Hummer to unleash an attack at the Convention Center where votes are being counted in Philadelphia.

Police tell Action News they found a weapon and two people were transferred to Central Detectives.

However, it's unclear how or if the people are connected to the investigation.

Early Friday morning, the Hummer was still on 13th Street near Vine. The vehicle had a window sticker and a hat with the logo for the internet group QAnon known for spreading conspiracy theories.
The FBI has labeled them a domestic terror threat.
