Wild footage shows at least 50 thieves ransacking freight train in Chicago as cops rush to the scene and service is ground to halt

At least 50 thieves descended on a freight train in Chicago's West Side to ransack whatever items they could get their hands on. 

The group of wayward opportunists swarmed the Union Pacific train on Friday to steal multiple boxes before officers arrived. 

The robbery occurred just before 4pm in the 400 block of North Lamon Avenue in the South Austin neighborhood. 

The massive heist forced the train to suspend its operations. In a statement on X.com, Metra said that 'train service is temporarily suspended due to ongoing police activity near Kedzie.'

The statement continued: 'Metra encourages customers to seek alternate transportation at this time.'

Crazy footage taken of the scene revealed the coordinated nature of the robbery.

People can be seen scrambling over the tracks to an open freight container where several men are busy removing boxes.

The men then hand the cargo off to other people who carry them across the tracks to waiting trucks.

When authorities arrived, they drew their firearms and aimed them toward one of the vehicles,

They put the number of thieves somewhere between 50 to 150, ABC7 reported.

This isn't the first time that this railway has been targeted for a robbery. In August, thieves looted a freight train near Lawler and Kinzie in the city's West Side. 

The thieves were able to spirit away an impressive haul, including several boxes containing TVs. 

In a statement, a Union Pacific spokesperson condemned the brazen theft.

'Rail burglaries pose a safety threat to the public, our employees and local law enforcement officers,' the official said. 

Authorities are actively investigating the incident, although it is unclear if any arrests have been made. 

Chicago authorities could not be reached for comment at this time.
