Prince George's County police have arrested the man wanted for allegedly setting fire to his estranged wife Monday morning at the T-Mobile store in Clinton where she worked.

The woman, 31, was flown to a hospital with third-degree burns, the most serious level, covering half her torso and face, police said. She was listed in serious condition yesterday, officials said.

Officers arrested Roger B. Hargrave, 33, of Temple Hills in an abandoned home in District Heights late Monday after police obtained a warrant charging him with attempted murder and assault. He will have a bond review hearing at 1 p.m. today.

According to police, a half-dozen customers were shopping at the T-Mobile store in the 8900 block of Woodyard Road about 10:30 a.m. when a man walked in clutching a 20-ounce Sprite bottle filled with gasoline.

He saw his estranged wife working behind the counter and doused her with the gasoline. He chased her out of the store, still throwing gas on her, then struck a match and threw it at her.

With flames covering her, the woman stumbled back inside. A customer threw a towel on her, extinguishing the flames.

Police said the woman and her husband split in July after a rocky marriage that had lasted several years. They are legally separated, police said.

She obtained a year-long protective order against him in July, but last month she asked a judge to rescind the order, which he did, according to court documents.

Hargrave has a history of arrests and convictions for drugs, gun crimes and robbery, court documents show.
