Home near Washington DC explodes as police surround armed suspect who had been firing flares

Officers were called to the home in Arlington, Virginia, at 16:45 EST (21:45 GMT) on Monday after reports of someone firing a flare gun.

When they tried to enter, there were shots fired then a big explosion.

Officers on the scene reported only minor injuries while the suspect inside the home is unaccounted for.

The incident started when the suspect fired a flare gun between 30 to 40 times, Arlington police said, which did not cause any injuries or property damage.

No real official word I've seen, but it appears Yoo was paranoid/delusional/antigovernment (and now deceased).

Years of lawsuits

Mr Yoo's social media accounts indicated that he spent years filing legal claims and alleging conspiracies with little evidence to back them up.

He posted videos online of documents from a number of lawsuits that accused people of stalking, threatening and harassing him.

Mr Yoo's claims were consistently thrown out by the courts.

Dave Sundberg, assistant director of the FBI's Washington field office, said that Mr Yoo had contacted the bureau several times over the years making allegations of fraud, but none of the messages resulted in any investigations.
