Man faces domestic arson and other charges after his estranged wife told police she came home to find him pouring gasoline on floor.

PORTSMOUTH — A local woman returned home with a friend Sunday evening to find her estranged husband pouring gasoline on the floor and threatening to set the house on fire, police said.

Portsmouth police responded to 182 Armando Drive at 8:18 p.m. for a report of a 75-year-old man who violated a no-contact order and broke into the home through a glass window.

When officers arrived they found the suspect, Chong Yoon, holding a samurai sword, police said. Officers told him to drop the sword, at which point Yoon attempted to run and had to be restrained, police said.

Yoon was charged with fifth-degree domestic arson, domestic breaking and entering, resisting arrest and violation of a protective order.

He was transported to Newport Hospital by police because of injuries sustained prior to the arrest.

Yoon was arraigned Monday in District Court before Judge Colleen Hastings. He did not enter pleas to the charges, which is typical for felony cases first heard in District Court. Yoon was ordered held without bail at the Adult Correctional Institutions in Cranston as a violator, according to a court clerk. His next court date is May 7.

Portsmouth police said 182 Armando Drive was his former residence but he had been staying elsewhere because of the protective order.

“We had to vent the premises” with fans in order to blow fresh air into the house and electricity to the house had to be cut to ensure the gasoline fumes didn’t reach a flammable or explosive level, Portsmouth Fire Department Chief Paul Ford said on Monday.

As of Monday afternoon, the house was habitable again, he said.

Ford, who responded to the scene, recalled talking with a colleague en route to the house.

“This is a new one,” he said.
