Residents of a luxury high-rise building on Manhattan’s Upper East Side are being terrorized by a sniper taking shots at their building. 

Police believe the gunman fired from Roosevelt Island across the East River at random on at least two different occasions. The first bullet, fired last Friday, hit an apartment on the 32nd floor. The second bullet, fired the next day at 1:15 a.m., hit a window on the 14th floor.

The shattered windows are now covered with plywood.

A woman named Ilene who lives on the 22nd floor of the targeted building told Inside Edition she's living in fear.

"You are nervous," she said. "I am certainly afraid to be by the window."

Rents in the targeted building start at $7,000 a month for a two-bedroom apartment. On Tuesday, police were spotted inside trying to figure out exactly where the bullets came from. It's believed the weapon used was a .38 caliber Smith & Wesson revolver. 

Former DEA special agent David Katz said even at a long distance a .38 caliber handgun can be deadly.

“It's not that far a shot,” Katz said. “They're not effective as far as accuracy, but still it'll hit that glass and possibly hurt or kill somebody.”

He said the people in the building should “absolutely” be nervous.
