A 30-year-old woman was stabbed to death by her boyfriend early Saturday in Queens, police said.

Authorities were called to a building on Van Cleef Street near Saultell Avenue in Flushing at about 4:15 a.m. for an assault in progress, officials said.

When they arrived, they found the unidentified woman lying inside with several stab wounds with a bloody knife nearby, cops said.

She was pronounced dead at the scene.

Investigators canvassed the neighborhood and busted the woman’s boyfriend just a few blocks away from the scene, his clothes covered in blood.

He was taken into custody and charges were pending, cops said.
