An alleged sex worker fell to her death in Queens during a police raid over the weekend.

It happened Saturday night, when officers stormed a massage parlor on 40th Road in Flushing.

Sources tell NY1 the spa was being investigated for illegal sex activities.

Police say they were trying to catch the 38-year-old woman when they saw her fall to the sidewalk from a third floor window.

She suffered serious injuries, and died Sunday at the hospital.

The medical examiner will determine the exact cause of death.
