MANHATTAN — A transgender woman has died after being assaulted in Manhattan back in April, police sources said Thursday.

The attack happened around 10:30 p.m. April 25 at 343 7th Ave.

Paramedics responded to find the victim with head trauma.

Police sources say authorities were not notified by the hospital or EMS of the incident, but when they were notified of the death, an investigation revealed the assault at the location.

The victim died from her injuries on May 4.

Councilman Corey Johnson said he was “saddened and angered” to learn the woman had died, and that if criminality was found to be involved in her death, “all resources must” be used to apprehend those involved.

“There must be zero tolerance for acts of violence, particularly against transgender individuals, who are disproportionately targeted by hate crimes and discrimination,” Johnson said.

The New York City Anti-Violence Project said the group’s thoughts and prayers are with the victim’s family, and that anyone can contact its 24 Hour English/Spanish hotline at 212-714-1141.
