FBI raid Halal meat plant in Illinois

Too much news today. This is strange though. In a collar county of Chicago. CBS2:

The government workers inside First World Management meat packing plant in Kinsman Monday wouldn't say why they were there or why scores of FBI agents and Immigration and Customs Enforcement agents were there Sunday.

The trouble is the FBI isn't saying much about what happened at this rural Grundy County plant. A spokesman confirms that the plant, which has a Muslim prayer room, was raided as part of an ongoing criminal investigation.

Some more info:

Neighbors who saw the raid on Sunday told CBS 2 it was a huge operation, involving more than 100 agents, police officers and even what one believed to be National Guard troops.

Sources say during the raid, the driveway was filled with more than 50 government vehicles. There was a helicopter flying overhead and a command center set up. On top of it were government sharpshooters with rifles at the ready.

There are apparently only six employees at the plant.
