Police have arrested a man they say stabbed two men over a parking dispute before plowing his car into a group of pedestrians in Queens on Sunday morning, according to sources. One person was killed and six others were hurt in the attack.

"This white car just hopped on the sidewalk and just drove straight into, like, the whole crowd. Everybody, and just hit everybody, and just continued driving," a witness said. "He didn't stop, he didn't slow down or anything, just [went] boom and continued driving."

Investigators said it started around 4:37 a.m. outside the XS Hookah Lounge on Liberty Ave. in South Ozone Park after the driver of a white Hyundai got into an argument with a BMW.

Sources tell NY1 that the pedestrian bystanders got involved in the dispute before the driver of the Hyundai got out of his car and stabbed a 29-year-old man and a 28-year-old man — who were inside the BMW — each in the torso.

The pedestrians who intervened in the parking dispute then left the scene toward Liberty Ave., but not before the Hyundai driver plowed into them with his car, according to sources.

Richardo Chattergoon, a 23-year-old man from Far Rockaway, one of the men the driver hit with his car, was pronounced dead at a local hospital, sources said. Five other hit-and-run victims are in stable condition.

The 29-year-old who the driver stabbed is in critical condition with a head injury and a stab wound. Sources said he was also run over in the hit-and-run.

The 28-year-old who was stabbed is in stable condition at Jamaica Hospital.

Sources tell NY1 that the Hyundai driver, a 22-year-old man from Far Rockaway, showed up at Jamaica Hospital around 5 a.m. with a laceration wound. He was then taken into custody after he was identified.

His car was recovered near the hospital, sources said.

The investigation is ongoing.
