At least three people were injured at an ICE facility in Dallas before a suspected sniper was found dead from a self-inflicted gunshot wound on a nearby rooftop.

The situation unfolded at the Texas facility around 7am on Wednesday morning.

The three victims were detainees in ICE custody, Fox4 reported.

Shortly after multiple people were wounded in the shooting, a suspected gunman was found dead on the roof of a nearby immigration attorney’s office.

ICE Director Todd Lyons confirmed that the shooter is ‘down’, but did not elaborate on how the suspected gunman died.

The status of all those injured in the shooting is not yet clear, however reports say that some were left in critical condition.

Images showed a large police presence descended on the scene.

This is a developing story and will be updated as information is confirmed.

he ICE facility has been frequently targeted by pro-immigration demonstrators in recent months.

In a nearby ICE facility in Alvarado, Texas, another attack took place on July 4 where 10 people were arrested for shooting at law enforcement officers.

Armed assailants with tactical gear were charged with terrorism and aggravated assault for the attack, which officials said at the time was intended to disrupt the ICE facility’s operations.
