Wild NYC car chase ends on Upper East Side blocks from Gracie Mansion with armed robbery and thief on the loose — VIDEO

A wild car chase ended with an armed robbery in broad daylight Saturday on a quiet Upper East Side street a few blocks from Gracie Mansion, police and witnesses said.

A black Mercedes sedan zoomed past a silver Toyota RAV4 driving against traffic down Second Ave. near E. 91st St. around 4:40 p.m., and ultimately slammed and spun the Toyota near E. 92nd St., police and witnesses said.

Then, the unhinged Mercedes driver used his car to push the Toyota onto a wide stretch of sidewalk, where the chase continued, video obtained by the Daily News shows.

The Mercedes rammed into the Toyota a second time, forcing it to spin around and become cornered on the sidewalk.

“Then one guy got out [of the Mercedes],” said a witness, who gave his name as Nour, 22, who said he worked at Yorkville Deli Market.

The video shows a man with a blue mask covering his chin exit the Mercedes and then proceed to pound at the Toyota’s windshield with a gun.

“He’s got a gun! He’s got a gun!” a passerby yelled.

The Toyota driver, who police said was 55 years old, stepped out of his car with his hands up and the armed man snatched a bag from inside the car, witnesses told The News.

Nour said the stunned victim told him there was cash in the bag.

“The guy was in shock he cannot say nothing. He just standing in his place,” Nour said. “At first when he see the gun… He get out and he put his hands up.”

Police were investigating the incident on Saturday evening.
