Dallas, TX (RT) — Dallas police are in a standoff with one or more armed men in a van, who earlier fired several shots at the local police department and left several bags of explosives near it.

A bystander uploaded this video of the incident (warning: strong language).

There was gunfire in front of the Dallas Police Department headquarters as a suspect rammed police cars and attempted to flee. The standoff at Interstate 45 that followed involved a SWAT team.

After the attack, several bags were found near the headquarters building. One was discovered to contain homemade explosives. Police are checking the remaining three.

One of the bags exploded on its own, Dallas Police Major Max Gerontweeted.

Another suspicious package was found under a police truck at the department’s parking lot. All the discovered explosives and suspected explosives have been disarmed.

To block the van, police had to shut down Interstate 45.

At a news conference about the incident, police told the media there might be up to four suspects in the van. The name one of the suspects gave police during negotiations is connected to several earlier cases of domestic violence. Police say they cannot confirm whether the suspect gave them his real name.

Police say the 50-year-old man blames them for losing custody of his son, and claims they accused him of being a terrorist.

Dallas Police Major Max Geron says no officers were injured during the attack, chase or standoff. The suspect the police are talking to says they wounded him.

The suspect’s van was intercepted near the town of Hutchins. Police are concerns the van might be carrying more explosives.
